Motor Current: Measure and document current in each stage for every new motor. Contain measurement of the engine terminal voltages (if engine terminals are somewhat inaccessible, i.e. submersible motors, take voltage studying in the engine control ) and engine currents once the motor has been operated at normal operating loads. For motors that are a part of flexible frequency use trueRMS-reading tools in making the measurements.
