Voltage Interruptions
The Logger records two types of interruptions:
•
All measured RMS values of input voltages that are < 1% of the
nominal voltage. (This threshold can be adjusted in PQ Log.)
•
Interruptions > 10 ms (0.5 line power periods).
The start time and duration of each interruption are registered.
