Induction Motor Protection (Part3)
Electrical Faults (Part4)
Inter-turn faults on the same phase are difficult to detect because they do not cause appreciable change in the current drawn by the motor. However, such faults cause hot spots to develop, leading to deterioration of insulation.
No specific protection against inter-turn faults is needed for most motors except very big motors. Embedded temperature detectors may be relied upon to provide protection against inter-turn faults.
