Two step residual overvoltage protection ROV2PTOV (59N) function calculates the
residual voltage from the three-phase voltage input transformers or measures it from a
single voltage input transformer fed from a broken delta or neutral point voltage
transformer.
ROV2PTOV (59N) has two voltage steps, where step 1 can be set as inverse or definite
time delayed. Step 2 is always definite time delayed.
