GROUP # / PROTECTION / TIME OC-NEQ / (+)TIME OC-NEQ / Curve
Range
A(101), B(117), ..., DEF-10S (Total 62 curves)
Default
US-VI
Select desired curve type for
(+)Negative sequence time overcurrent
element. For more details, refer to
“Table 8-2.
CB time-current
operation characteristic setting range”
.
GROUP # / PROTECTION / TIME OC-NEQ / (+)TIME OC-NEQ / Time Dial
Range
0.05 ~ 15.00
Default
1.00
Step
0.01
Set time dial, multiplying this value to selected T-C curve. Multiplying
this value changes the slope of the curve. Time dial is conducted after
time add application.
GROUP # / PROTECTION / TIME OC-NEQ / (+)TIME OC-NEQ / Time Add
Range
0.00 ~ 600.00 sec
Default
0.00
Step
0.01 sec
Set time adder to add set value on selected T-C curve.
GROUP # / PROTECTION / TIME OC-NEQ / (+)TIME OC-NEQ / M.R.T
Range
0.00 ~ 10.00 sec
Default
0.00
Step
0.01 sec
T-C curve trip operation is faster than trip time, this set value is added
to T-C curve for more delay. This function can be useful for other
protective device and line fuse coordination.
GROUP # / PROTECTION / TIME OC-NEQ / (+)TIME OC-NEQ / Reset Method
Range
INST, LINEAR
Default
INST
Step
~
In case that a fault current is decreased under pickup level,
(+)Negative
sequence time overcurrent
protection is reset.
.INST :
After 1 cycle, Reset.
LINEAR:
When the fault value is reached at selected curve’s RT
(Reset characteristic constant) value, Reset.
