UMG 605
(Power Analyzer for DIN RAIL)

Overview
Power quality analysers

Power quality analysers for DIN rails - continuous monitoring of the power quality e.g. EN 50160.

Harmonics
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.
Alarm Management
The alarm management feature in GridVis® monitors all measurement parameters captured by the UMG measuring devices. It comprises escalation management, a logbook function and user management for individual notifications by e-mail, dialogue box on the monitor, etc.In addition to monitoring effective values, short term interruptions and transients, as well as communication with the measuring devices can also be monitored.
Flicker
Flicker refers to the subjective impression of visibly noticeable brightness fluctuations, caused by a temporal change to the light density or the spectral distribution. The cause is voltage variations. As of a specific threshold value, flicker occurrences become disturbing and harmful to health under certain circumstances. The standard DIN EN 61000-4-15 controls the details.
Reporting
Powerful RCM residual current monitoring already detects leakage currents in their initial stages before they cause system failures or even fires. It is already integrated in certain UMG measuring devices. The measuring current transformer that is required can be installed manually at a later date if required. Continuous RCM monitoring increases the system safety and availability significantly. In specific applications such as the data centre, residual current monitoring is essential due to the high availability requirements.
E-mail
A notification by e-mail is the ideal aid for alarm and escalation management for the UMG measuring devices and the GridVis® software. Recipients can therefore be informed of the details of an event immediately.
Memory
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.
