Beware of Asymmetry – Causes, Consequences, Measurement and Control
Published by Sonel Three-phase motors are overheating! Overcurrent breakers are triggering without a reason! Energy bills are higher than expected! Undesirable Asymmetry The economic benefits of energy suppliers and their users are strongly dependent on reliability, safety and efficiency of the power system. One of the phenomena that is strongly related to the efficiency ofContinue reading “Beware of Asymmetry – Causes, Consequences, Measurement and Control”

Stalled Motors
Published by Dranetz – BMI Case Studies In this case study, we look at an industrial customer with two 1250hp motors on a 4kV circuit, whose motors would not start. To determine the problem, we installed a Dranetz – BMI PP4300 at the motor input. The power monitoring instrument quickly identified the motor itself asContinue reading “Stalled Motors”
