Parameter: Duration of V-seal-in time
•
Default setting (_:104) Duration of V-seal-in time = 4.00 s
The parameter Duration of V-seal-in time limits the pickup seal-in induced by an overcurrent or
undervoltage. The value must be set higher than the value of the parameter Operate delay. The difference
shall be greater than 0.5 s. In the default setting, a difference of 1 s is used.
Parameter: Vph-ph< threshold
•
Default setting (_:105) Vph-ph< threshold = 60.000 V
With the parameter Vph-ph< threshold, you can set the threshold at which the output signal
Voltage
release
is activated when the minimum phase-to-phase voltage falls below this threshold.
Parameter: V2> threshold
•
Default setting (_:106) V2> threshold = 4.600 V
With the parameter V2> threshold, you can set the threshold at which the output signal
Voltage
release
is issued when V2 exceeds the threshold.
