Determine the input type, whether it is three-phase three-wire or three-phase four-wire, or single-phase measurement.
Determine the measurement signal, such as phase voltage, line voltage, current, power, frequency or power factor.
Determine the corresponding relationship between the measurement signal and the output signal, for example, AC 0-100V corresponds to DC 4-20mA.
Generally, our BD Series electrical transducer measures the secondary side signals. If it is necessary to correspond to the primary side signals, it is also necessary to increase the transformation ratio of the voltage transformer and the current transformer.
