If there are two transformer having rating of 2.5mva, 6.6kv/440v(satr-star),and the load is 600kw then what is better to maintain less losses in transformer having both transformer in parellel or only single transformer connected to load? Please give calculated answer
What is meant by short-pitched winding?
A 400 V, 50 Hz, Δ connected synchronous generator has a field reactance of 0.1 Ω and armature resistance of 0.015 Ω. At full load, the machine supplies 1200 A at 0.8 pf lagging. Under full-load conditions, the friction and windage losses are 40 KW and the core losses are 30 KW. What is the machine’s overall efficiency? Ignore any field circuit losses.
