How HT Motor Protection should be designed when running in parallel ...
In a commonly installed protection scheme for parallel-connected motors and capacitors, current sensed by CT will be less than the actual value. Suppose 3600 kW, 6.6 kV, 384 Amp FLC (0.82 P.F) Slip ring induction motor is running at full load without capacitor bank, then the motor will be taking 384 Amp normally. When connected in parallel with ...
