Voltage imbalance in motor circuits causes premature motor failure. The real cost isn’t the motor, but the lost production. A good power monitor implementation strategy can help you see these imbalances emerging, but what if you already have a toasted motor and suspect voltage imbalance? First, see how widespread the imbalance is. Do you see it only on that motor circuit, at the service, or propagating from some point between the two? Unless it’s at the service, the utility ...
