Measuring and testing on HV installations in power distribution and industrial environments is fraught with difficulties and dangers. There are technical challenges of generating high enough currents and voltages for reliable and accurate testing, without sacrificing the portability of the testing equipment, and ensuring proper ruggedness for operation in HV conditions. Proper overvoltage category is also of great concern, as it is inextricably linked with the safety of both the testing equipment and the operator. Even more, the safety requirements should likewise cover all supported/associated accessories, since they are often the weak link in the testing chain, endangering the tested object, the equipment and ultimately the operator.
Lofty requirements that are nevertheless perfectly fulfilled by our newest products, the MI 3143 Euro Z 440 V and MI 3144 Euro Z 800 V. Both were designed for measuring the effectiveness of automatic trip out protection in case of faults in transformers and other HV installations, but are suitable for many other HV testing/measuring applications due to their versatility. On top of that they can be used as adapters, in conjunction with selected instruments (MI 3155 EurotestXD, MI 3152 EurotestXC, MI 3152H EurotestXC 2.5 kV and MI 3325 MultiServicerXD) or in standalone mode, as instruments, and can be remotely controlled with an Android device.

The MI 3144 Euro Z 800 V is the premiere product with a full array of measuring and testing functions and capable of operating at higher voltages and currents, hence the cooling radiator on the front panel. It supports the following testing/measuring functionalities (features):
- High precision 4-wire 300 A Z Line and Z Loop impedance measurements.
- High range 800 V measurements on 16 ... 420 Hz AC networks.
- High range 440 V measurements on 16 ... 420 Hz AC networks.
- DC source & line resistance 3 ... 260 V DC measurements.
- High current dR 300 A 4-wire partial voltage drop measurements.
- High current dR 300 A 4-wire current’s path resistance measurements.
- Support for ELR type AC, A and B testing/measuring.
- Earth leakage relay (ELR) trip-out testing time and current measurements.
- ELR current injection testing.
- Ground fault analysis with contact, touch and step voltage.
- Floating voltmeter for partial contact results.
- One-clamp high current ground integrity method with clamps (flex & iron).
The MI 3143 Euro Z 440 V on the other hand is a more streamlined version of its more capable sibling and aimed at less demanding users with more basic requirements. Supported testing/measuring functionalities (features) are:
- High precision 4-wire 300 A Z Line and Z Loop impedance measurements.
- High range 440 V measurements on 16 ... 420 Hz AC networks.
- High current dR 300 A 4-wire partial voltage drop measurements.
- Ground fault analysis with contact, touch and step voltage.
- Floating voltmeter for partial contact results.
The MI 3143 Euro Z 440 V and MI 3144 Euro Z 800 V are available to order immediately.
