Answer Posted / kj
These are both used on a DG.
The short circuit maintenance CT is used to keep the output
voltage and current high enough to clear a fault by
tripping an overcurrent device (circuit breaker).
The droop CT is used to cause the voltage to decrease as
the kvar load rises. This is used to help DG's share the
kvar load.
