Abstract

A complete summary of techniques for monitoring and protecting each major component of a low voltage, line-connected induction motor is given in this paper. Specifically, a method for protecting the machine from thermal overload is presented, along with a method for robust stator turn-fault detection. Current-based spectral analysis for rotor and rotating faults, as well as bearing faults is also presented. Each of these techniques are proved to provide condition- and fault-related information to the user without additional sensors.
