A new method for detection of unbalance voltage supply in three phase induction motor
Induction motors are associated with various techno-economic advantages; therefore these are widely used in residential, commercial and industrial systems. Cost effective and reliable process of condition monitoring of induction motor is very important. It is found that unbalance voltage supply is o...

Induction motors are associated with various techno-economic advantages; therefore these are widely used in residential, commercial and industrial systems.

Induction motors are associated with various techno-economic advantages; therefore these are widely used in residential, commercial and industrial systems.

This is a sensor-less and online approach that accomplishes the reliable and accurate analysis of the induction motors.
