TheFC-2GB Lightning Protection Components Testeris essential for ensuring surge arresters and grounding systems function correctly, preventing equipment damage from lightning strikes.
Key Features
1、Multi-Functional Testing
Measures DC reference voltage (U1mA) of surge arresters (MOA).
Tests leakage current (0.75U1mA) to assess aging or degradation.
Checks insulation resistance of lightning protection components.
2、High Accuracy & Wide Range
Voltage Range: 0-30kV (for high-voltage arresters).
Current Range: 0-20mA (for leakage current testing).
Insulation Resistance: Up to 10GΩ (for dielectric strength).
3、Automatic & Manual Modes
Auto ramp-up voltage for U1mA testing.
Manual control for precise diagnostics.
4、Digital Display & Data Storage
LCD screen for real-time readings.
Stores test data for analysis and reporting.
5、Portable & Robust Design
Suitable for field testing in substations, power plants, and telecom towers.
Built-in safety protections (overcurrent, overvoltage).
Typical Applications
1、Surge Arrester (MOA) Testing – Verifies U1mA and leakage current to detect moisture ingress or degradation.
2、Lightning Rod & Down Conductor Inspection – Ensures low-resistance paths for lightning dissipation.
3、Grounding System Evaluation – Checks connections in lightning protection networks.
4、Preventive Maintenance – Identifies failing arresters before they compromise system safety.
How It Works
1、DC Reference Voltage (U1mA) Test
Applies increasing DC voltage until 1mA current flows through the arrester.
Records U1mA value (indicates the clamping voltage).
2、Leakage Current Test (0.75U1mA)
Applies 75% of U1mA and measures leakage current.
High leakage (>50µA) suggests degradation or contamination.
3、Insulation Resistance Test
Uses 500V or 1000V to check insulation quality.
4、Data Analysis & Reporting
Compares results with manufacturer specs.
Flags failed or aging arresters.
Advantages Over Traditional Methods
1、Faster & Safer – No need for separate HV power supplies.
2、More Reliable – Digital measurements eliminate analog meter errors.
3、Compliance Testing – Meets IEC, IEEE, and utility standards.
Safety Considerations
1、Disconnect arrester from the system before testing.
2、Discharge arrester fully after testing.
3、Use proper PPE (gloves, insulated tools).
