NettetMotors therefore in general are protected against the following faults: Stator faults. Rotor faults. Overloads. Unbalanced supply voltages including single phasing. Undervoltage. … NettetEarth-fault protection for a motor operating on an earthed neutral system is provided by means of a simple instantaneous relay having a setting of approximately 30% of the motor full load current in the residual circuit of three CTs. Operation of relay due to CT saturation during initial high starting current should be avoided.
