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".
16.1.7.5 Voltage and current sequence measurements VMSQI, CMSQI
SEMOD54417-299 v6
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
"Measurement
supervision".
