The contact wear of electrical distribution networks reclosers is calculated in percentage using the total number of close—Open operations. How is the calculation performed? Based on what formula and parameters? Any help is appreciated.
Dear all,
How can I determine the critical clearing time (CCT) of a fault in DIgSILENT?
How can I use DPL to determine the critical clearing time (CCT) of a fault in DIgSILENT?
Any help is appreciated.
Dear Mr. Mbrooke
I’d like to take this opportunity to thank you for the valuable assistance you’ve given me. You have generously shared your expertise and experience with me, and I truly appreciate the support. I sincerely appreciate the time you spent.
It is helpful to have someone who has had experience with similar issues . I appreciate your taking the time out of your busy schedule to write to me. I have some other questions. The most important is that how much the time interval between a recloser open and close should be? Suppose that...
I wanted to let you know how much I appreciated your help.I know how much time and effort you invested.You are a valued member. Could you please mention somewhere where this scheme is used (e.g. the mentioned utilities in the US and, if possible, the url of the websites to be more familiar with...
Dear all
Some say that it is better to locate the recloser near the substation; because as you know, 70-80 percent of the faults in electrical distribution networks are of transient (not permanent) type and so by doing this, most of the faults are cleared by the recloser in several seconds. The...
Thank you Desrod2 for your comments.
Could you please explain more about your method and your rule of thumb? Unfortunately I do not understand completely what you mean.
