The Model MW & MK measure active & reactive power, it can to measure a distorted sinusoidal wave with high harmonics or chopped SCR-conrolled waveforms. The ratio input model accepts a secondary signal from CTs & PTs and provides a direct reading. The direct input type is calibrated to the specified inputs to provide an accurate reading. |
