Electrical Signature Analysis (ESA) is an energized test method where voltage and current waveforms are captured while the motor system is running to assess the health of the motor system. Energized testing provides valuable information for AC induction and DC motors, generators, wound rotor motors, synchronous motors, machine tool motors, and more.

Electrical Signature Analysis (ESA) is an energized test method | ALL-Test ProMotor Circuit Analysis (MCA™) is a deenergized test method to assess the health of the motor and motor circuit. This method can be initiated from the Motor Control Center (MCC) or directly at the motor. The advantage to testing from the MCC is that the entire electrical portion of the motor system, including the connections and cables between the test point and the motor is evaluated.
