Anonymous Poster #1	Capacitor Fuse Blowing 10/16/2014 2:05 AM
	Dear All, If two fuses had blown out in a three phase star connected capacitor bank, I believe there will be no Kvar Output & no current will be drawn from the remaining other two phases.But if a single fuse blows out in a three phase star connected capacitor bank, Since the other two capacitor's will be in series and supplied by Line Voltage (L-L) 1.what will be the Current flowing in the other two phases? (In case of single fuse blowing) 2.What will be the Kvar output of the capacitor bank?(In case of single fuse blowing)

	Sounds like home work! What are you thinking 1 and 2 is? You should have at least an idea given your previous assumptions . . . __________________ Common Sense Dictates

	The rules of CR4 prevent members answering homework questions. Homework when I was studying made me do my own research and it made me learn. Some members don't understand that basic principal and will answer. They don't help the future of our profession. __________________ The reports of my death are greatly exaggerated.

	This sounds quite simple. However, when a phase is disconnected, system become imbalanced. Therefore, if you want to know the currents flowing through the two other phases, you must regard it as an asymmetrical fault occurring. So, its in turn complicated.
