QUESTION OF MOTOR STARTUPDear All,I’m trying to start-up a 10 kV-2 MW motor, with no load. But the protection relay tripped 3 times with "Negative Sequence Overcurrent Protection, I2>". I’ve checked the disturbance records, the voltages are perfect (there is no V2 or Vr), but the I2 is very high (startup current = ~760 A, I2 = ~60 A).
