Explanation of parameters
RunOnCPU
defines the processing unit which runs the function.
ParSet 4..1
Parameter for determining in which set of parameters a particular function is active (see Section 5.11.).
CurrentInp
Analogue current I/P channel.
All current I/P's are available for selection.
Angle
Characteristic angle for measuring real power. The phaseangle 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-toground 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.
PN
Reference value for the power being measured.
This enables the amplitude of the power being measured to
be adjusted, e.g. to take account of the rated power factor.
Voltage mode
Definition of the method of voltage measurement and therefore also the calculation of power. Settings:
phase-to-ground The voltage of the selected voltage I/P is
measured directly.
phase-to-phase The phase-to-phase voltage formed by
the selected voltage I/P and the cyclically lagging voltage channel is measured.
This setting is not permitted when only a
single-phase is connected or when
phase-to-phase voltages are connected.Setting instructions
The measurement function must be carefully set to obtain the
best accuracy. The following must be observed:
C.t./v.t. input channel reference values
The reference values for the voltage and current analogue
input channels must be set such that, when the rated values
are applied to the I/P's, 1.000 UN and 1.000 IN are measured
by the function.
In most cases, it will be possible to retain the default reference setting (1.000) for the c.t. and v.t. input channels. Note
that any changes made to the reference value of a threephase voltage or current I/P apply to all phases.
