Earth Fault Detected

🚨CRITICAL

An earth (ground) fault has been detected in the generator output circuit. Earth faults indicate dangerous leakage of current to ground, which can cause electrocution hazards, equipment damage, and fire risk.

🔍 Possible Causes

  • •Damaged cable insulation
  • •Water ingress in junction boxes
  • •Failed component with insulation breakdown
  • •Incorrect wiring or connections
  • •Earth leakage in connected load
  • •CT wiring fault giving false reading

🔧 Troubleshooting Steps

  1. 1Disconnect loads and check if fault clears
  2. 2Use insulation tester to check cable megger values
  3. 3Inspect all junction boxes for moisture
  4. 4Check generator winding insulation resistance
  5. 5Verify CT and earth fault relay wiring
  6. 6Systematically reconnect loads to isolate faulty circuit

❓ Frequently Asked Questions

What insulation resistance is acceptable for a generator?

Minimum acceptable insulation resistance is typically 1 megohm per kV of rated voltage, measured with a 500V or 1000V insulation tester. New equipment should be 100+ megohms.

Is it safe to run with an earth fault?

No. Earth faults create electrocution hazard and fire risk. The generator should be shut down and the fault located and repaired before resuming operation.
