VoltageInp
defines the v.t. voltage input channel. Only three-phase v.t’s
can be set and the first channel (R phase) of the group of
three selected must be specified.
I-Start
Pick-up current at which the characteristic becomes effective.
Angle
Characteristic angle.
c-Setting
Setting for the exponential factor determining the operating
characteristic according to BS 142.
k1-Setting
Constant determining the parallel shift of the characteristic.
t-min
Definite minimum operating time, operating characteristic
constant.
IB-Setting
Base current for taking account of differences of rated current
I
N
.
tWait
Time allowed for the directional decision to be received.
MemDirMode
determines the response of the protection after the time set
for memorising power direction:
· trip
· block.
MemDuration
Time during which the power direction last determined
remains valid.
Receive
Input for the signal from the opposite end of the line:
T: not used
xx: all binary inputs (or outputs of protection functions).
Ext Block
F: not blocked
xx: all binary inputs (or outputs of protection functions).
Trip
Tripping signal.
