LQHV-546 Arrester Discharge Counter Validation System

Essential Maintenance for Lightning Protection Systems

This 8/20μs surge generator performs mandatory annual testing of arrester counters per utility maintenance protocols. Validates both lightning strike recording and system protection triggering with >100A impulse currents.

Technical Parameters

Critical Testing Functions

1. Counter Verification

• Simulates actual lightning strikes (8/20μs)

• Validates mechanical/electronic counters

• Tests up to 10 consecutive strikes

2. System Protection Check

• Confirms arrester triggering threshold

• Detects moisture-damaged monitors

• Identifies contact corrosion

Why Annual Testing Matters

Industry studies show:

• 23% of arrester counters fail within 5 years

• Moisture ingress causes 68% of failures

• Unrecorded strikes mask protection gaps

3-Step Test Procedure

1. Connect: Clip leads to counter terminals

2. Test: Generate 1-10 standard surges

3. Verify: Confirm counter increments match
