Measuring Values
Voltage - Measured Values
VT
In general, the first measuring input of the measuring card is used as the reference angle.
Only if the amplitude of the reference phase drops away will the next phase be used as the reference for angle
calculation. For this the following order is used:
•
Channel VL1, VL2, VL3, VL12, VL23, VL31, IL1, IL2, ...)
Voltage Transformer Signals (Output States)
Signal Description
Phase seq. wrong Signal that the device has detected a phase sequence (L1-L2-L3 / L1-L3-L2)
that is different from the one that had been set at [Field settings / General
Settings] »Phase Sequence«.
