The MI 3144 Euro Z 800 V is a multifunctional, portable battery (Li-ion) or mains powered test instrument with excellent IP protection: IP65 (case closed), IP54 (case opened). It 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. The MI 3144 Euro Z 800 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 and DC circuits, high current dR 300A loop and line measurements for testing of partial currents and partial voltage drops, it is ideal for testing in industrial settings. It 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.
