Characteristic Value
Operate time accuracy in definite time mode ±1.0% of the set value or ±20 ms
Operate time accuracy in inverse time mode
±5.0% of the theoretical value or ±20 ms
3)
Suppression of harmonics RMS: No suppression
DFT: -50 dB at f = n × f
n
, where n = 2, 3, 4, 5,…
Peak-to-Peak: No suppression
P-to-P+backup: No suppression
1) Measurement mode = default (depends on stage), current before fault = 0.0 × I
