A ground fault went undetected, damaging the neutral earthing resistor. We supported immediate recovery and performed a full scheme analysis with updates, training, and future-proofing recommendations.
We quickly assessed the fault impact and helped restore operations by realigning key protection settings to allow safe startup without compromising detection.
Detailed analysis of event records and protection logic revealed missed detection paths and gaps in sensitivity underground fault conditions.
We provided updated settings, training, and documentation to ensure system-wide awareness and better coordination under future fault scenarios.
