I browsed a new book on fault analysis at a bookstore. It discusses also the relevant standards and recommended practices, among them the UK Engineering Recommendation ER G7/4. What is the role or status of this recommendation? If I were going to carry out fault analysis for a UK customer (not...
I am trying to compare the short circuit currents in a partial network "fed" by
1) the secondary (or tertiary) of a transformer connected in delta with one phase grounded ("corner grounded delta")
2) the secondary (or tertiary) of a transformer connected in a grounded wye (Yn)
There may be...
A free short-circuit / load flow program (for small networks) can be downloaded at http://pp.kpnet.fi/ijl. It is still under development. It uses the superposition method for the initial short-circuit current. It does not (yet?) follow any standards.
Feedback is welcome.
(if you need...
