4.23.7. Maximum apparent power protection
General description
It is a protection against excessive increases in the generated
power.
The operation is similar to the previous. The protection will
trip the corresponding relay when the generated apparent
power is greater than the set value. There are two units with
dierent ranges for the additional time, HI-Set and LO-Set.

4.24.1. General description
This function produces an "event" and a control signal, when
there is a number of trips higher than programmed during
the programmed time, passing to denitive trip. When
manual closing occurs, the period of time is reinitialized.
An event is also generated each time when, after a trip,
the ∑kI
2
counter exceeds the programmed threshold (it
is a pole to pole treatment). While on this situation the
corresponding signal is sent to control.
For the pole wear calculation, the wished type of calculation
can be programmed, between kI
2
*t, kI
2
and kI
1. If kI
2
is chosen, the kA
2
is calculated, being I the current
measured after passing the waiting time set after the
trip.
2. If kI is chosen, only the sum of currents in kA is calculated
being I the current measured after passing the waiting
time set after the trip.
3. If kI
2
*t is chosen, the KI
2
/100 value is accumulated every
10 ms being I the current measured after passing the
waiting time set after the trip. It nishes accumulating
when I < 0.05 A.
The trip and close circuit supervision allows the checking of
the continuity of circuits with up to 2 trip coils and 2 close
coils, when the breaker is close and also when it is open (see
the connection example n the following page).
