how does calculate loss correction factor in transformer1 2275
how rated the neutral voltage of transformer and reactor, e.g. 400/220, 200MVA transformer have neutral voltage of 33kv. and reactor voltage 145kv. how this rating decided?
How neutral voltage for transformer decided? eg 33kv neutral voltage for 200MVA transformer?
1))why we run three phase or three different circuit from a single conduit 2)) why not two circuit of different phase run in same conduit?? and why we run same three cicuit of same phae run in single conduit??
