Functionality
The current circuit supervision function CCRDIF is used for monitoring current
transformer secondary circuits.
CCRDIF calculates internally the sum of phase currents (I_A, I_B and I_C) and
compares the sum against the measured single reference current (I_REF). The
reference current must originate from other three phase CT cores than the phase
