We are planning to synchronized DG's with our captive plant in the event of black start of plant, but before sync we checked voltage of DG with our plant voltage and it varies from 5 V to 450 V. So in this condition how we can sync DG with plant ?
How to calculate the heat load for a electrical room
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?
