I want Primary side delta and Sec side Star connection transformer . but i have received Star - Star transformer ,shall i use the same transformer by giving the only 3 ph on Primary side without Neutral connection on the Starpoint.
5 7257Why current flows in nutral? As per theory there should be no current in 3 ph explain.

How can calculate the rating of a servo stabilizer for given a specific load
A 7 storey building has a floor area of 35,000sq.ft on each storey. On the ground floor 11KV electrical sub-station is to be erected. A load of 3kw for every 400sq.ft (p.f is 0.8) is proposed for each floor. fire pump 7.5hp, water pump 5hp, lift 2 nos, each 10hp and 20shop load of each shop is 5kw. calculate a. load each floor b. total load of building c. L.T feeders for aech floor and from transformer to main. d. distribution diagram e. capacity of sub-station/capacitor bank f. line diagram
how is the connection of a 3 phase ct trivector meter done on a pole mounted transformer
Practical condition in 400KV Sub station:- Breaker(open) , isolator(open), Earthing (close) at both end e.g A & B. Now Open A Stn Earthing than Open B stn Earthing (Which have a 50MVA reactor) , AND suddenly show R,Y,B phase 704KV,573KV,118KV respectively. Que is without closing of breaker how it is possible.????
