Operation principle
Four step residual overcurrent protection, zero or negative sequence direction EF4PTOC
(51N/67N) function has the following four “Analog Inputs” on its function block in the
configuration tool:
1. I3P, input used for “Operating Quantity”.
2. V3P, input used for “Voltage Polarizing Quantity”.
3. I3PPOL, input used for “Current Polarizing Quantity”.
4. I3PDIR, input used for “Operating Directional Quantity”.
These inputs are connected from the corresponding pre-processing function blocks in the
Configuration Tool within PCM600.
