Transient Detection

2.5.7
2.5.7.1

Transients

The device detects temporary overvoltages as transients if the instantaneous value of the primary rated
voltage exceeds the parameterized reference value at one or several sampling points. Detect and capture tran-
sients as short as 100 μs at 50 Hz (80 μs at 60 Hz).
The following data and values are determined during the evaluation of the transients in the device:
•
Serial number of the event
•
Time when transients start to occur (time stamp with date and time)
•
Affected phase (a, b, c, ab, bc, ca)
•
Transient duration
Parameterized reference value (in %) is up to 240 % of the primary rated voltage.
