Operation
52 Current before = 0.0 × In, fn = 50 Hz, overcurrent in one phase, results based on statisti-
cal distribution of 1000 measurements
53 Includes the delay of the signal output contact
54 Negative-sequence current before = 0.0, fn = 50 Hz, results based on statistical distribu-
tion of 1000 measurements
55 Includes the delay of the signal output contact
