8BCONTROL FUNCTIONS
PROTECTION, CONTROL AND METERING FUNCTIONS
If the voltage level is below Vzero during the time Tzero, then the trip command
of the Capacitor Bank is issued, as it is assumed that there is no voltage on
the busbar.
If the voltage is below Vmin, and above Vzero, during the time Tmin, then the
close command is issued.
If none of the above cases occur (Voltage is between Vmin and Vmax) then the
"Clock" algorithm operates if a switching time scheduled has been defined.
You may define two time slots for weekdays and two for holidays. You may also
configure whether Saturday is considered holiday or not. The algorithm constantly
checks which time slot is for connecting or disconnecting the capacitor bank
according to the configuration that has been given.
Figure 2-76 shows this algorithm
