Case-3: FU ER & F-LOWER both set as Capacitive:
There are two F set points to be set in A FC 06. The U ER limit and
the LOWER limit. A FC 06 ensures that F-U ER is never exceeded.
Additionally, “No change band” to minimum kVAr band size equal to
smallest bank kVAr x 1.5 ensures no hunting during the low kW loading.
A FC 06 is normally set for F settings as per first two diagrams shown
where F LOWER is inductive. This philosophy helps to optimize the
system maximum kVAr to be used as well as reduces the number of
switching operations during higher loading conditions. This ensures better
life expectancies of the switched capacitors as well as the switching
devices.
This methodology of kVAr compensation reduces the complex settings
that are used by conventional F relays. The settings like C/K ratio and
kVAr offsets/shifts are eliminated which makes A FC 06 user friendly and
thus easy to commission.
