outputs and IEC 61850. This is achieved by magnitude and angle compensation at 5,
30 and 100% of rated current. The compensation below 5% and above 100% is
constant and linear in between, see figure 456.
Phase currents (magnitude and angle) are available on the outputs and each magnitude
output has a corresponding supervision level output (Ix_RANGE). The supervision
output signal is an integer in the interval 0-4, see section
Phase-phase and phase-neutral voltage measurements VMMXU,
VNMMXU
The voltage function must be connected to three-phase voltage input in the
configuration tool to be operable. Voltages are handled in the same way as currents
when it comes to class 0.5 calibrations, see above.
The voltages (phase or phase-phase voltage, magnitude and angle) are available on the
outputs and each magnitude output has a corresponding supervision level output
(Vxy_RANG). The supervision output signal is an integer in the interval 0-4, see
section "Measurement supervision".
Voltage and current sequence measurements VMSQI, CMSQI
The measurement functions must be connected to three-phase current (CMSQI) or
voltage (VMSQI) input in the configuration tool to be operable. No outputs, other than
X_RANG, are calculated within the measuring blocks and it is not possible to calibrate
the signals. Input signals are obtained from the pre-processing block and transferred to
corresponding output.
Positive, negative and three times zero sequence quantities are available on the outputs
(voltage and current, magnitude and angle). Each magnitude output has a
corresponding supervision level output (X_RANGE). The output signal is an integer in
the interval 0-4, see section
Function block
The available function blocks of an IED are depending on the actual hardware (TRM)
and the logic configuration made in PCM600.
