8.4.7 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.
8.4.7.1 Operating quantity within the function
The function always uses Residual Current (3I
be:
1. directly measured (when a dedicated CT input of the IED is connected in PCM600 to the
fourth analog input of the pre-processing block connected to EF4PTOC (51N/67N) function
input I3P). This dedicated IED CT input can be for example, connected to:
