Display examples
The backlighted graphical display (5,7“) of the UMG 511 enables the presentation of measurement values in numerical form, as a bar chart
or as a line graph. Selected displays can automatically be displayed in alternation (automatic display rotation). The instrument is program-
med using userfriendly clear text menus or the GridVis software.
Example of a UMG 511 connection illustration
Measurement in a four-phase network with main
measurement and auxiliary measurement
Main measurement
The UMG 511 has 4 measurement channels for
current and voltage. The first three channels
(main measurement) are intended for use in a
three-phase system.
Auxiliary measurement
The auxiliary measurement can be used for mea-
surement in a single-phase or symmetrical three-
phase system. Alternatively, the current input
can be allocated to the three-phase system of the
main measurement for measuring the neutral-
conductor current. For example, the voltage
input could then be used for recording the vol-
tage between the neutral conductor and PE. The
auxiliary measurement provides all measure-
ment parameters like in the main measurement
(current, voltage, power, harmonics, transients,
events and flicker).
