Features & function:
- Test functions: voltage drop, radio errors and phase difference between the ports of the energy meters and the PT secondary port of sing/three phase electricity energy metering device.
- Voltage drop, radio errors and angle difference (phase) are displayed on one screen.
- Test admittance, conductance and susceptance of PT, which are display on one screen.
- Data storage 200 groups with storage time of up to 10 years.
- The tested CT information of the energy metering device can be download through the communication port of the host device
- The host device offers zero self-calibration functions.
- The host device offers abnormal self-inspection function, identification function for wiring correctness and alarm function of measured voltage exceeding the limits.
- Protection functions of under-voltage, over-voltage and over-current
