8.2.7 Operation principle
This function has the following three “Analog Inputs” on its function block in the
configuration tool:
1. I3P, input used for “Operating Quantity”. Supply the zero-sequence magnitude
measuring functionality.
2. V3P, input used for “Voltage Polarizing Quantity”. Supply either zero or negative
sequence voltage to the directional functionality
3. I3PPOL, input used for “Current Polarizing Quantity”. Provide polarizing current to
the directional functionality. This current is normally taken from the grounding of a
power transformer.
4. I3PDIR, input used for “Directional detection”. Supply either zero or negative
sequence current to the directional functionality.
These inputs are connected from the corresponding pre-processing function blocks in the
Configuration Tool within PCM600.
