There is one breaker arcing current element available per CT bank, with a minimum of two elements. This element calcu-
lates an estimate of the per-phase wear on the breaker contacts by measuring and integrating the current squared passing
through the breaker contacts as an arc. These per-phase values are added to accumulated totals for each phase and com-
pared to a programmed threshold value. When the threshold is exceeded in any phase, the relay can set an output operand
to "1". The accumulated value for each phase can be displayed as an actual value.
