what is the difference b/w ATS and HTS?
If a transformer primary winding operates at 240v, the secondary at 120v and the load is 1500w & the transformer is rated at 92% efficient, what's the current flowing through the primary winding of the transformer? What is the formula for finding this?
Why frequency changes due to load variation in power system ? i.e why when load increases frequency decreases?
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?
