Explanation of parameters:
ParSet 4..1
Parameter for determining in which set of parameters a par-
ticular function is active (see Section 5.11.).
Trip
Definition of the tripping logic (matrix) excited by the
function's output.
V-Setting
Voltage setting for tripping.
Delay
Time between start signal at the I/P and the tripping signal at
the O/P.
Forbidden setting:
£ 1 s for voltage settings £ 0.2 U
N
.
VT-Compens
Amplitude compensation factor for the residual voltage I/P,
enabling different transformation ratios of the main v.t's for
phase and residual voltages to be equalised.
The polarity of the residual voltage can be reversed by enter-
ing negative values.
