Equal-potential Three Phase Energy Meter Test Instrument( Split Type)

Overview:

The RT6303E Equal-potential Three Phase Energy Meter Test Instrument is an ideal new-generation multi-position embedded energy meter test instrument. The 6303E energy meter test instrument comprises of power source, standard energy meter and error processing system which can be widely used in testing various single/ three phase watt-hour meters and multifunction watt-hour meters of Grade 0.2 or lower. Among all its features, the equal-potential testing method is specifically suitable for testing such watt-hour meters of Grade 0.5 or lower where the voltage and current measurement loops cannot be separated or where the voltage and current measurement loops may be separated to improve calibration and testing efficiencies, such three phase energy meters where the voltage and current measurement loops cannot be separated during testing. One of this energy meter test instrument’ s important features is that its modulation amplifier’ s high output and load capacity matches the three phase active separation CT to bring you a more convenient and reliable calibration in embedded energy meters.
