why the transformer secondary voltage is more than the load end voltage like t/f 11KV/433V for 415V(terminal voltage)
4 11751how netral CT is selected (including its details specification)
ABB, ABC, dbpl, Mecon, Shree Engineering, Tapasya Transformers,
8 43863Different STANDARDS (BS, IS, IEC etc) gives different informations on CT specification. How they correspons w r t each other (i.e I mean to say BS provides "knee point voltage" but IS does not, then how can i select CT)

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.
