Metrel MI 3144 Standard EURO-Z 800V Multifunction Tester

The MI 3144 Euro Z 800 V Multifunction Tester is designed to measure the effectiveness of automatic trip out protection in case of faults in transformers and other high voltage equipment. Perfect for in-field use as is a portable battery-powered unit (mains powered also for when you are back at base).

This unit offers excellent IP protection: IP65 (case closed), IP54 (case opened).

It is ideal for testing in industrial setting due to its high precision line and loop impedance measurements on AC and DC circuits, high current dR 300A loop and line measurements for testing of partial currents and partial voltage drops.

The Metrel MI 3144 also supports contact voltage measurements, ELR electrical leakage relay testing with fault current injection, trip-out time measurement and DC source, line, battery and accumulator measurements.

The Metrel MI 3144 can be controlled via an Android app A 1522 aMESM, MI 3152 EurotestXC, MI 3152H EurotestXC 2.5kV, MI 3155 EurotestXD or MI 3325 MultiServicerXD.
