MAXIMUM GENSET FREQUENCY ALARM

UnclassifiedElectrical

What This Code Means

Power obtained (mains or genset) is negative; Power exceeds the programmed factor of the nominal power; Power obtained (mains or genset) is negative and exceeds the programmed factor threshold; Genset frequency values obtained are kept over the maximum programmed limits; Erroneous order in the maximum voltage values of the genset (not phase 1, phase 2, and phase 3 in order); Power is out of the programmed limits

Possible Causes

  • •Erroneous wiring of the current transformers
  • •Genset frequency exceeds maximum programmed limits (Thresholds table parameter 5)
  • •Device is configured to work with three-phase with neutral or three-phase without neutral and detects an incorrect phase sequence

Suggested Actions

  1. 1Correct the wiring of the current transformers
  2. 2Immediate engine stop
  3. 3Stop with engine cooling
