What is OLTC AND RTCC and it's function?
Answer Posted / bala
OLTC means On Load Tap Changer and It is coming with transformer. If it is fitted, no need to worry about the incoming voltage whether it is high or low as the transformer will automatically change its tap position to deliver the constant output voltage.This is possible only when we interface the AVR to it.
RTCC means Remote Tap Changer Control Panel. We can change the transformer tap position from remote area. This is possible only when the interfacing between OLTC and RTCC has been done.

I have an existing old MCCB. ABB Model SACE, the rating are: Ue = 660 volts, Iu =1250 Amps, 3 poles, Ith (max) =800 amps at 45 deg C. I need a circuit breaker for my 3 phase motors, 380 volts 60 hz. the supplier required the minimum ampacity of the breaker to be 911 amps. can i use this breaker with rating of Iu =1250 amps but Ith = 800amps maximum?
