1. Project Overview
1.1 Background
Reservoirs rely on interconnected facilities, including dams, gate hoist rooms, dispatch buildings, hydrological stations, surveillance cameras, weather sensors, and communication systems. However, their open surroundings and proximity to water increase exposure to lightning strikes, induced surges, and ground potential rise, which can damage equipment and disrupt operations.
With over 20 years of experience, Henan Yangbo Lightning Protection Technology Co., Ltd. provides integrated lightning protection solutions for water infrastructure and other industries. In addition, we have delivered lightning protection design and installation services for the first and second reservoir areas of Fenhe Reservoir.
Based on relevant standards and engineering experience, we integrate lightning early warning, external lightning protection, surge protection, intelligent monitoring, and coordinated grounding into a comprehensive reservoir lightning protection system.
The solution references GB 50057-2010, GB/T 39437-2020, and GB 50601-2010, while the applicability of IEC 60060-1 and IEC 61083-1 requires further verification. Furthermore, the system combines lightning location equipment, atmospheric electric field instruments, thunderstorm detectors, weather stations, YBZ-DPD80 lightning protection devices, insulating support poles, surge protective devices, and grounding monitoring equipment.
As a result, the integrated solution supports early warning before thunderstorms, effective protection during lightning events, and continuous monitoring and traceability afterward.
1.2 Protection Objectives
Our solution addresses five main objectives:
External lightning protection: Protect dam structures, equipment rooms, outdoor cameras, and monitoring terminals against direct lightning strikes through an appropriately designed protection system.
Lightning early warning: Provide advance alerts when thunderstorms approach, giving reservoir operators time to take precautions and shut down selected outdoor equipment where necessary.
Internal surge protection: Coordinate power and signal surge protective devices to reduce transient overvoltages and protect PLCs, cameras, hydrological sensors, and communication equipment.
Intelligent online monitoring: Monitor lightning events, current peaks, grounding performance, and surge protective device status through a centralized platform.
Long-term grounding performance: Combine low-resistance composite grounding electrodes with hollow ion-enhanced grounding devices where site investigations support their use, helping manage grounding performance in challenging soil conditions.
1.3 Protected Facilities and Equipment
Our solution addresses the following protection targets:
Buildings: Reservoir dispatch offices, gate hoist rooms, hydrological monitoring buildings, and distribution rooms.
Outdoor equipment: Dam surveillance cameras, PTZ cameras, water-level gauges, rain gauges, seepage pressure sensors, and gate control terminals.
Monitoring systems: Weather stations, lightning location equipment, atmospheric electric field instruments, and thunderstorm detectors.
Communication and transmission systems: Fiber-optic network equipment, 4G/5G communication modules, RS485 signal links, and power supply lines.
2. Overall System Architecture
We organize the integrated reservoir lightning protection system into four functional layers.
2.1 Lightning Detection and Early Warning
Our proposed detection layer combines a single-station lightning location system, an explosion-protected atmospheric electric field instrument where required, a thunderstorm detector, and a multi-parameter weather monitoring system.
These instruments collect lightning-related and meteorological data, including electric field changes, lightning locations, rainfall, temperature, humidity, wind speed, wind direction, and atmospheric pressure. The system then uses the available measurements to support thunderstorm risk assessment and warning notifications.
2.2 External Lightning Protection
The proposed external protection system combines the YBZ-DPD80 passive wide-angle direct lightning protection device with fiberglass-reinforced polymer (FRP) insulating support poles.
We propose these devices for selected high points on the dam, monitoring stations, and surveillance installations. The final arrangement must follow the approved lightning protection design and a verified protection-zone assessment.
2.3 Internal Surge Protection
We use coordinated power and signal surge protective devices to protect electrical and electronic systems.
Depending on the installation, the protection network covers distribution panels, RS485 communication lines, Ethernet connections, video signals, analog sensor circuits, and antenna feeder lines.
2.4 Grounding and Intelligent Monitoring
The proposed grounding network combines low-resistance composite grounding electrodes with hollow ion-enhanced grounding devices where appropriate. We connect the building lightning protection systems, equipment protective grounding, and functional grounding according to the approved grounding design.
Meanwhile, lightning current peak monitors, grounding resistance monitoring modules, and surge protective device status monitors send data to the Yangbo intelligent lightning protection cloud platform. Operators can then review system status, receive alerts, and track maintenance requirements.
3. Lightning Detection and Early Warning
Our early warning system helps reservoir operators identify developing thunderstorm risks and take preventive action before lightning activity reaches critical facilities.
3.1 Atmospheric Electric Field Lightning Warning Instrument
Recommended installation locations: Elevated points on the dam and rooftops of hydrological or meteorological monitoring buildings.
Proposed quantity: One or two units, subject to the site assessment.
The instrument monitors atmospheric electric field changes associated with thunderstorm development. The original project specification proposes a warning lead time of 10–30 minutes and three warning levels: Attention, Warning, and Danger.
Key proposed specifications include:
Communication interfaces: RS485 or NB-IoT
Operating temperature: -40°C to +70°C
Enclosure protection: IP67
System integration: Reservoir dispatch system and intelligent lightning protection platform
Actual warning lead time and accuracy depend on the instrument’s detection method, local atmospheric conditions, installation location, and validation results.
3.2 Lightning Location System
We propose installing lightning location equipment at suitable elevated points within the reservoir area.
The project specification identifies a monitoring radius of approximately 20–40 km for cloud-to-ground lightning activity. The system records lightning location, occurrence time, and estimated current amplitude.
Operators can use these records to identify actual lightning activity around the reservoir, assess local exposure, and evaluate protection performance over time. The final monitoring range depends on the selected equipment, antenna or sensor arrangement, terrain, and detection technology.
3.3 Thunderstorm Detector
The thunderstorm detector works alongside the atmospheric electric field instrument to identify thunderstorm development and movement.
By combining complementary observations, the system can improve the assessment of local thunderstorm conditions and help operators distinguish thunderstorm activity from ordinary weather changes.
3.4 Multi-Parameter Weather Monitoring System
Our proposed weather monitoring station integrates sensors for:
Rainfall
Wind speed and direction
Temperature and humidity
Atmospheric pressure
Where the design permits, we can install the weather station alongside lightning detection equipment on a shared support structure. The monitoring platform can then combine meteorological measurements with lightning data to support a more complete risk assessment.
The system can deliver alerts through local audible and visual alarms, platform notifications, and configured SMS or mobile notifications.
4. External Direct Lightning Protection
The proposed external protection design uses YBZ-DPD80 passive wide-angle direct lightning protection devices with FRP insulating support poles where suitable.
The supplied product specification describes a dual-mechanism approach involving the proposed mitigation of downward lightning leaders and the interception and discharge of lightning current. The effectiveness of these claimed mechanisms requires independent technical validation and must not replace a compliant conventional lightning protection design without engineering approval.
4.1 Dispatch Buildings, Gate Hoist Rooms, and Distribution Rooms
We recommend the following design measures, subject to the building classification and approved drawings:
Install roof lightning protection conductors or a suitable air-termination network. The original proposal specifies a mesh size no greater than 10 × 10 m; the designer must verify the appropriate mesh dimensions against the applicable standard and lightning protection class.
Bond rooftop metal ventilation ducts, railings, and other exposed conductive components into the equipotential bonding system.
Assess the suitability and placement of YBZ-DPD80 devices at selected rooftop high points.
Route dedicated copper down conductors along short, direct paths to the common grounding network. The original proposal specifies an insulated copper conductor cross-sectional area of at least 50 mm².
Evaluate the use of structural reinforcement as part of the down-conductor system where the building design and applicable standards permit. Provide the required number and distribution of down conductors according to the approved design.
4.2 Dam Crest, Outdoor Surveillance Poles, and Hydrological Monitoring Points
For elevated dam monitoring points and hydrological stations, we propose FRP insulating support poles where the mechanical and electrical design supports their use.
The original proposal places a YBZ-DPD80 device at the top of selected poles and routes a separate copper down conductor independently toward the grounding network.
Important installation requirement: An FRP support pole serves as a mechanical support, not as a lightning current down conductor. The installer must provide a separate, appropriately sized down-conductor path and follow the approved clearances and bonding requirements.
For outdoor surveillance cameras, water-level gauges, and rainfall monitoring terminals, the design team must verify the actual protection zone for every device. Where necessary, engineers should provide local air terminals and suitable bonding and grounding arrangements.
The proposal references the rolling sphere method and a 45 m rolling sphere radius for Class II lightning protection. Engineers must confirm the correct radius and protection class for each structure under the applicable standard rather than applying one value to every location.
4.3 YBZ-DPD80 Technical Specifications
The following values come from the supplied product information and require confirmation against the current product datasheet and applicable test reports.
| Parameter | Supplied specification |
| Model | YBZ-DPD80 |
| Claimed lightning current capacity | ≥200 kA |
| Claimed protection angle | ≥80° |
| Weight | 10 ± 0.5 kg |
| Wind resistance | 40 m/s |
| Operating temperature | -40°C to +70°C |
| Power supply | No external power required |
| Main material | 316 stainless steel |
| Product configuration | Passive design |
The product description identifies two proposed functions: mitigation of downward lightning leaders and interception and discharge of lightning current. Independent verification must establish the actual performance, protection coverage, and suitability for each installation.
5. Internal Lightning Protection and Surge Protection
Lightning-induced electromagnetic transients can travel along power and signal cables into control rooms and monitoring facilities. Therefore, we recommend a coordinated surge protection design based on the lightning protection zones (LPZ) applicable to each installation.
The proposed design considers the transition from LPZ 0A and LPZ 0B to LPZ 1 and LPZ 2, with surge protective devices selected and coordinated according to the electrical system, exposure level, and equipment withstand voltage.
5.1 Power Surge Protection
We propose a staged protection arrangement:
Main distribution entrance: Install a suitable Type 1 surge protective device where the lightning protection design requires it.
Building and equipment distribution panels: Install coordinated Type 2 surge protective devices.
Outdoor monitoring cabinets and data acquisition boxes: Install suitable downstream surge protective devices to protect camera and sensor power supplies.
Install SPD connections as short and direct as practical, and coordinate the protective devices with the grounding and bonding network. The original design sets a target lead length of no more than 0.5 m; the final arrangement should comply with the applicable installation requirements.
5.2 Signal Surge Protection
We recommend selecting signal SPDs according to the interface and electrical characteristics of each circuit.
RS485 circuits: Protect water-level, rainfall, and gate-control sensor communication lines.
Ethernet networks: Protect network connections for surveillance cameras and other outdoor devices.
4–20 mA analog circuits: Protect process instrumentation and monitoring sensor signals.
Antenna feeder lines: Select appropriate RF surge protective devices for the frequency range and system configuration.
Correct matching helps maintain signal integrity while reducing the risk of surge damage.
5.3 Equipotential Bonding
We propose the following bonding measures:
Install an equipotential bonding bar in each equipment room and connect cabinets, switches, PLC enclosures, and UPS enclosures according to the approved design.
Bond outdoor equipment boxes, metallic camera poles, and hydrological equipment enclosures to the appropriate grounding network.
Design cable shield bonding, metallic conduit bonding, and entry-point bonding according to the signal interface, electromagnetic compatibility requirements, and grounding arrangement.
These measures help control potential differences and improve the overall coordination of the lightning protection system.
6. Grounding System
6.1 Integrated Grounding Network
Reservoir sites may contain gravel, rock, and high-resistivity soil. In such environments, conventional galvanized steel electrodes may experience corrosion and seasonal changes in grounding performance.
The proposed solution combines YBZ-DSJ low-resistance composite grounding electrodes with hollow ion-enhanced grounding devices, subject to geotechnical investigation and design verification.
The project proposal identifies the following grounding resistance targets:
General target: ≤4 Ω
Difficult sites: up to 10 Ω under the proposed alternative arrangement
These values do not automatically apply to every reservoir facility. The responsible designer must establish the required acceptance values for each building and equipment system according to the applicable standards, protection requirements, soil conditions, and equipment specifications.
6.2 YBZ-DSJ Low-Resistance Composite Grounding Electrode
The supplied product information identifies the YBZ-DSJ as a vertical grounding electrode made from a graphite-carbon composite material.
Product specifications
| Parameter | Specification |
| Model | YBZ-DSJ |
| Dimensions | Ø78 × 1,000 mm |
| Material | Composite graphite-carbon material |
| Main characteristics | Conductivity, corrosion resistance, and convenient installation |
| Typical applications | Deep-well grounding, high-resistivity soil, corrosive environments, and sites with difficult excavation |
The product uses a composite material designed to provide electrical conductivity and corrosion resistance. Its modular configuration supports vertical deep-well installation and may help installers reach deeper soil layers when site conditions allow.
The supplied technical description lists a resistivity test result of ≤0.226 μΩ·m, a flexural strength of ≥13.7 MPa, and a service-life claim exceeding 50 years. Customers should confirm the test methods, units, product construction, and supporting documentation before using these values in project specifications.
The product description also identifies several installation and material options, including graphite connecting bolts, flexible graphite conductors, galvanized flat steel, copper-plated flat steel, pure copper conductors, and tinned copper. The installer must select compatible connection methods and apply suitable corrosion protection at each joint.
6.3 Hollow Ion-Enhanced Grounding Device
The proposed hollow ion-enhanced grounding device uses a cylindrical, corrosion-protected structure. The supplied description states that its internal moisture-retaining and ion-release design helps improve the conductivity of surrounding soil.
The original installation proposal specifies:
Horizontal burial depth: 0.8–1.0 m
Spacing between adjacent devices: at least 3 m
Multiple devices connected in parallel where required
Corrosion protection at welded joints
Fine-soil or approved grounding backfill, followed by layer-by-layer compaction
The actual performance depends on soil chemistry, moisture, groundwater conditions, installation quality, and the product’s verified design. The engineering team should confirm compatibility with the site and the manufacturer’s documented installation requirements before use.
6.4 Grounding Network Construction
We propose separate local grounding arrangements for the dispatch building, gate hoist room, and dam monitoring station, interconnected through suitable conductors to form a coordinated reservoir grounding network.
The installation team should:
Connect all designated down conductors and equipment grounding conductors to the approved grounding network.
Verify bonding continuity and connection integrity.
Install grounding resistance monitoring points where the system design requires online monitoring.
Test the completed system and record the results for acceptance and future maintenance.
7. Intelligent Online Lightning Protection Monitoring
Our proposed intelligent monitoring system helps operators view system status, investigate lightning events, and plan maintenance through a centralized platform.
7.1 Lightning Current Peak Monitor
The original proposal uses solar-powered monitoring units with Rogowski coils installed around selected lightning down conductors.
Depending on the selected model, the system records lightning event time, current peak, and polarity. It supports NB-IoT or RS485 communication and uploads historical data for subsequent analysis.
7.2 Online Grounding Resistance Monitoring
We propose monitoring points at the dispatch building, gate hoist room, and dam monitoring station.
The monitoring modules track grounding performance and can issue alerts when measured values exceed configured thresholds. This approach helps operators identify potential deterioration and investigate grounding problems without relying solely on periodic manual measurements.
The selected instrument must use a measurement method suitable for the actual grounding network and installation conditions.
7.3 SPD Status Monitoring
The proposed SPD monitoring module checks available device status indicators and, where the selected product supports them, leakage current and temperature.
The platform can notify maintenance personnel when an SPD reports a fault or reaches a defined replacement threshold. Actual monitoring functions depend on the SPD and its associated monitoring module.
7.4 Mechanical Lightning Strike Counter
The proposal includes the YBZ-JX3000 passive mechanical lightning strike counter on selected down conductors.
Operators can read the counter locally and compare its recorded event count with the online monitoring records where the system supports that comparison.
7.5 Intelligent Lightning Protection Cloud Platform
The platform can consolidate the following information:
Lightning early warning data
Lightning location records
Meteorological measurements
Lightning current peak records
Grounding resistance measurements
SPD operating status
It can also support alert notifications, historical trend analysis, report exports, and integration with the reservoir dispatch system, subject to interface compatibility.

| Dam surveillance points and water-level or rainfall terminals | Verified lightning protection coverage; suitable power and signal SPDs; enclosure bonding; grounding connections according to the approved design |
The engineering team must confirm the quantity, exact model, protection class, installation height, and grounding configuration for each area after completing the site survey and risk assessment.
9. Main Product Technical Specifications

10. Key Installation and Construction Requirements
10.1 External Lightning Protection
Do not use an FRP support pole as a lightning current down conductor.
Install an independent down conductor and keep its route as short and direct as practical.
The original proposal places the YBZ-DPD80 device 1.5–2 m above the equipment it intends to protect. The designer must verify this height against the approved protection-zone calculations and installation requirements.
10.2 SPD Installation
Keep connecting conductors short and direct.
Coordinate upstream and downstream power SPDs according to the expected surge current and energy requirements.
Match signal SPDs to the circuit’s voltage, current, frequency, and communication interface.
10.3 Grounding Construction
Use deep-well installation where the site design requires the grounding electrode to reach deeper soil layers.
Use approved backfill materials and avoid construction waste in grounding trenches.
Remove welding residue and apply suitable corrosion protection to joints.
Maintain the specified minimum spacing of 3 m between hollow ion-enhanced grounding devices where the approved design uses that arrangement.
10.4 Cable Protection
Select shielded outdoor signal cables where appropriate.
Design cable shield bonding according to the grounding and electromagnetic compatibility requirements.
Protect exposed cables with suitable metallic conduits and bond the conduits according to the approved design.
10.5 Early Warning Equipment Installation
Select a location that provides suitable exposure to atmospheric conditions and minimizes nearby obstructions.
Install solar-powered equipment so that its photovoltaic panel receives adequate sunlight; the original proposal specifies a south-facing orientation for the northern hemisphere.
Verify local solar exposure, sensor clearances, communication coverage, and maintenance access before final installation.
11. System Commissioning, Testing, and Acceptance
We recommend a structured commissioning process to verify equipment operation and system integration.
11.1 Individual Equipment Testing
Check the operation of early warning instruments, monitoring terminals, SPDs, and grounding monitoring modules. Confirm the communication interfaces and status indicators for each device.
11.2 Integrated System Testing
Verify cloud platform data uploads, alarm notifications, historical records, and the communication interface with the reservoir dispatch system.

11.4 Handover Documentation
Provide the reservoir operator with the applicable completion drawings, equipment certificates, test reports, operating instructions, and maintenance manuals.
12. Operation and Maintenance
A regular maintenance program helps preserve the performance of the integrated lightning protection system.
Annual pre-season inspection: Before the local thunderstorm season, inspect external lightning protection devices, fasteners, SPDs, and grounding connections for corrosion or damage.
Daily monitoring: Review online alerts and investigate abnormal grounding measurements, SPD fault indications, and lightning warnings promptly.
Annual independent inspection: Arrange third-party lightning protection testing at the interval required by applicable regulations and the site’s maintenance plan.
Thunderstorm safety: Keep personnel away from exposed lightning protection equipment and grounding conductors during thunderstorms. Follow the site’s emergency procedures and avoid areas where step or touch voltages may create hazards.
