Motor Current Signature Analysis
The output of a Motor Current Signature Analysis (MCSA) is presented using the Electrical Motor Performance Analysis & Trending Hardware (EMPATH), produced by Framatome Inc. in the USA. This instrument applies the MCSA technique, by directly acquiring data from the Motor Control Centre (MCC) while the equipment is energized.
A current transformer that is clamped around the supply leads on all phases to sense the motor currents, either directly for LV motors or at the secondary side of the current transformer for MV motors. For the voltages, they are taken straight from the secondary side of the voltage transformer for the MV Motor and the voltage leads for the LV Motor.
Collected current and voltage data can be used to indicate, but not limited to, the followings:
