Multifunction power analyser

The UMG 96S is a measurement instrument of the newest generation which is suitable for measuring, recording and monitoring electrical parameters (True-RMS) in low and medium voltage networks (1 and 3-phase systems with a neutral conductor).


Many UMG measuring devices have their own memory containing typical recording ranges of up to 2 years. Recording is freely configurable. A 128 megabyte memory can record around 5,000,000 values.

In order to record work values securely and precisely for individual consumers, the UMG measuring devices have an extensive selection of tariffs of up to 14 items depending on the device type. Of course, they differentiate between effective energy (consumption, supply and without backstop) and reactive energy (inductive, capacitive and without backstop). This can be used to record high and low tariffs separately for example.

Harmonics occur due to operating equipment with a non-linear characteristic, e.g. transformers used in saturation, energy saving bulbs, frequency converters and power electronics. They cause a load on the mains due to additional currents and can affect or even destroy operating equipment. This mains feedback can be detected and documented using power quality analysers.
