GENSET VOLTAGE ASYMMETRY ALARM

UnclassifiedElectrical

What This Code Means

Amperage values are kept over the maximum programmed overload limits during the stabilization time; Difference between any pair of real voltage values among generating set voltage phases (VG12, VG23, or VG31) is over the maximum asymmetry programmed limits

Possible Causes

  • •Amperage value is superior to the maximum programmed overload limit (Thresholds table parameter 7) but under the maximum limit of short-circuit (Thresholds table parameter 8) on the checked phases
  • •Voltage difference between genset phases exceeds the maximum asymmetry programmed limits (Thresholds table parameter 4) during the stabilization time

Suggested Actions

  1. 1Stop with engine cooling
