Metrel MI 3143 Euro Z 440 V Transformer/HV Equipment Tester

The Metrel MI 3143 Euro Z 440 V is intended for measuring the effectiveness of automatic trip out protection in case of faults in transformers and other HV equipment. With its high precision line and loop impedance measurements on AC circuits, high current dR 300A loop and line measurements for testing partial voltage drops and contact voltage measurement, it is ideal for testing in industrial settings.

 

The MI 3143 can be controlled via one of the following devices:
