13.2 Power quality
The "Power Quality" (PQ) area gives you the option of retrieving the PQ status with a clear overview
according to common standards. Here you have access to continuous monitoring of the power quality
according to:
·
IEC 61000-2-4
PQ for customer-supplied power grids
The evaluation takes place via indicator (quick evaluation), as well as within the Watchdog App
(temporal evaluation). The class of 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:
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.
The display using the traffic light principle allows events that do not comply with the respective
quality agreements to be identified without in-depth knowledge.
