13.2 Power quality
In the "Power Quality" (PQ) area, you have the option to retrieve the PQ status with a clear overview ac-
cording to common standards. Here you have access to permanent monitoring of power quality accord-
ing to:
· EN 50160 PQ for energy supply networks
· IEC 61000-2-4 PQ for customers’ supply networks
The evaluation takes place via indicator (quick evaluation), as well as within the Watchdog app
(temporal evaluation). The class of the IEC 61000-2-4 can be temporarily changed within the indicator
settings. However, this has no lasting effect.
A change of the class is reset to class 2 ("compatibility level as in the public network") after leaving the
page.
If you have installed further apps for the power quality, there are additional menu items in the "Power
quality" menu:
1. For the app "IEC 61000-2-4 Watchdog":
· IEC 61000-2-4 settings
· IEC 61000-2-4 Watchdog
Changing the IEC 61000-2-4 class in the watchdog settings changes the class permanently in the
watchdog, as well as in the indicator.
2. For the app "EN 50160 Watchdog":
· EN 50160 settings
· EN 50160 Watchdog
The display using the traffic light principle allows the events that do not comply with the respective quality
agreements to be identified without in-depth knowledge.
