Explanation of parameters
ParSet 4..1
Parameter for determining in which set of parameters a par-
ticular function is active (see Section 5.11.).
CurrentInp
Defines the c.t. input channel.
All current inputs are available for selection.
Angle
Characteristic angle for measuring real power. The phase-
angle is also taken into account when measuring apparent
power.
The default setting of 0.0 degrees should not be changed,
when voltage and current I/P’s are in phase when measuring
purely real power, e.g. when measuring the phase-to-ground
voltage and current of the same conductor.
The setting may vary from 0.0 in the following cases:
· compensation of c.t. and v.t. phase errors
· compensation of the phase-shift between phase-to-
ground and phase-to-phase voltages
· compensation of the phase-shift between voltage and
current in general (e.g. when measuring S-T voltage and
R current).
VoltageInp
Defines the v.t. input channel.
All voltage I/P’s are available for selection.
