2) Inrush Duration Fault Pickup Current Setup
GROUP #/ PROTECTION/INRUSH RESTRAINT / PICKUP CURRENT/ Phase
Range
10 ~ 20000A
Default
2000
Step
1A
Phase fault current level is configured during inrush current restraint
duration. If the phase current is greater than the setting value, the
delay curve of the phase time overcurrent element is activated.
GROUP #/ PROTECTION/INRUSH RESTRAINT / PICKUP CURRENT/ Ground
Range
10 ~ 20000A
Default
2000
Step
1A
Ground fault level is configured during the inrush current restraint
duration. If the ground current is greater than the setting value, the
delay curve of the ground time overcurrent element is activated.
GROUP #/ PROTECTION/INRUSH RESTRAINT / PICKUP CURRENT/ S.E.F
Range
0.1 ~ 2000.0A
Default
20.0
Step
0.1A
Sets the sensitive earth fault current level during the inrush current
restraint duration If S.E.F current is greater than this setting, a
sensitive earth fault element will operate.
GROUP #/ PROTECTION/INRUSH RESTRAINT / PICKUP CURRENT/ Neg Seq’
Range
10 ~ 20000A
Default
2000
Step
1A
Sets the negative sequence fault current level during the inrush current
restraint duration. If the negative sequence current is greater than the
setting value, the delay curve of the negative sequence time
overcurrent element operates.
NOTE:
The above setting applies the pickup current to operate the time overcurrent element, and the
multiple of current pickup current which is applied to the T-C curve during the time
overcurrent operation applies the pickup current setting value of the delay curve.
