UMG 605: the extra compact power analyser
Added value through additional functions
T
hanks to state-of-the-art digital signal processor, it is possible to offer the
power quality analyser UMG 605 at a very reasonable price. The high sam-
pling rate enables a continuous measurement of more than 2000 measured
values per measurement cycle (200ms). The UMG 605 power quality ana-
lyser serves the purpose of continuous monitoring of the power quality e.g.
in accordance with EN 50160. This serves the purpose of monitoring the
supply power quality from the energy supply side. The UMG 605 can also
be used in applications for failure analysis on the consumer side and is also
used as a preventative measure for network perturbations.

Applications
The power quality analyser which is equipped with 4 current and voltage inputs collects and digitalises the effective values (True
RMS) from currents and voltages in 40-70Hz (15-440Hz) networks. The integrated microprocessor calculates the electrical para-
meters from the sampling values. The relevant voltage can be defined as a phase-neutral or a phase-phase voltage for measurement
in a three-phase system. The voltage serves the UMG 605 as a reference voltage for harmonic measurement, transient and event rec-
ording and for the flicker meter. A nominal current can be set using this for the measurement of electrical current events. However,
it is generally used for measuring the current in the neutral or PE conductor or used for measuring a voltage difference between N
and PE.
