How To Check Motor Winding Resistance On Single & Three-Phase Motors
Motor Circuit Analysis™ (MCA™) is a test method that determines the true state of health of 3 phase & single-phase electrical motors. MCA™ checks the motors coils, rotor, connections, and more. MCA™ can verify ac motor winding resistance as well as dc motor resistance and determine state of health.

How High Resistance Imbalances Can Damage Your Electric Motors
A small, but critical, motor in a pulp and paper mill exhibits a changing and rising resistive imbalance indicating a power circuit anomaly. If the motor fails, the loss of production costs could be up to $20,000 per hour. Follow along as they test and investigate the problem.
