5.1.3 Functionality
The transformer inrush detection INRPHAR is used to coordinate transformer
inrush situations in distribution networks.
Transformer inrush detection is based on the following principle: the output signal
BLK2H is activated once the numerically derived ratio of second harmonic current
I_2H and the fundamental frequency current I_1H exceeds the set value.
The operate time characteristic for the function is of definite time (DT) type.
The function contains a blocking functionality. Blocking deactivates all outputs
and resets timers.
5.1.4 Operation principle
The function can be enabled and disabled with the Operation setting. The
corresponding parameter values are "On" and "Off".
