5 64933what is the relation between KVAR,KVA,KW?why we are mentioning capcitor rating in kvar?what is meant by arcing horn and horn gap in transformer?what is equipotential wire?
1 7007What is the method to calculate the capacitor bank rating for say 50 KW load and how do we connect each capacitor to busbar??
4 13599In our factory so many iron pillors are exists for supporting the shed/Hangar. If do more no of earthings at one piller instead of doing more earth pits in many locations and running earth strip around the hanger, I can save the money. Please suggest this method is acceptable as per Is specifications though the Earth resitance of the farthest piller is with in the limits as per IS specifications.

why do we need to use 3c+3e cable, normally i select only 3c+e cable and i think it is enough. pls explain the usefull of 3e cable ( in this project the earthing system is well done)
we have two generators different capacity on 15 MW and other 6MW at 11 KV , 15 MW gen. bus short level current 40KA,and 6MW short level current 25KA,, length of cable 100MTR between 6 MW from 15MW gen. for bus coupling . kindly tell any one can we use both NGR OR one NGR from any GEN. BOTH NGR has diff. rating. Tariq pakistan
