Primary, Nominal current and Rated secondary values are entered via parameter setting in
PCM600 (IED Configuration / Configuration / Analog inputs/Current (3I, CT))

Unless otherwise specified, the
Nominal Current
setting should always be the same as the
Primary Current
setting which is a reference value for protection functions.
Each setting parameter of current protection functions is divided by application nominal cur-
rent I
