7.2.2
Functionality
The four step residual overcurrent protection, zero or negative sequence direction
(EF4PTOC, 51N/67N) has independent inverse time delay settings for step 1 and 4.
Step 2 and 3 are always definite time delayed.
All IEC and ANSI inverse time characteristics are available.
EF4PTOC (51N/67N) can be set directional or non-directional independently for each
of the steps.
The directional part of the function can be set to operate on following combinations:
•
Directional current (I3PDir) versus Polarizing voltage (V3PPol)
•
Directional current (I3PDir) versus Polarizing current (I3PPol)
•
Directional current (I3PDir) versus Dual polarizing (VPol+ZPol x IPol) where
ZPol = RPol + jXPol
IDir, VPol and IPol can be independently selected to be either zero sequence or
negative sequence.
