Power quality analyser
UMG 511 Power quality analyser
A
dded value with additional functions
The UMG 511 power quality analyser serves for the purpose of continuous monitoring of the power qua-
lity e.g. in accordance with EN 50160. This serves for the purpose of monitoring the supply power quality
from the energy supply side. The UMG 511 can also be used in applications for failure analysis on the con-
sumer side and is also used as a preventative measure for network perturbations. A rapid, cost-optimised and
r
eliable communication system can be developed through the Ethernet connection. The instrument’s own
homepage offers you the opportunity to call up the data or configure the instrument directly using the em-
bedded web server.
The large number of digital inputs and outputs offer a variety of
communication systems possibilities and allows connection to
PLC systems and independent control tasks. The GridVis
analysis software represents a fundamental part of the standard
delivery. The GridVis can be used to practically trigger analysis
in accordance with EN 50160 with the click of a button. The
presentation of online data and the analysis of historical data is
also a benefit for finding the root cause of network problems.

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 parameters from the sampling values. The relevant voltage can be de-
fined as a phase-neutral or a phase-phase voltage for measurement in a three-phase system. The voltage ser-
ves the UMG 511 as a reference voltage for harmonic measurement, transient and event recording and for
the flicker meter. A nominal current can be set using this for the measurement of electrical current events.
The 4th current and voltage input represents a separate measurement system. 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.
