Sensor-based HV electrical energy meter adopts the form of measurement for metering high voltage power directly. This product contains non-traditional high-voltage sensor, which make use of weak current and voltage outputs. This kind of sensor replaces the traditional electromagnetic-type current and potential transformer, which adopts a direct metering method to measure high-voltage electrical energy. As high voltage and current conversion equipment, this product can convert them directly to signals which match with the metering chip. With this product, the conversion equipment and the electrical energy metering module are designed and integrated to measure high-voltage electrical energy.
