hii.i am a B.TECH(EEE) graduate.i want 2 know wat type of qusns r asked in sbi clerk interview 2 candidates like me??kindly post answers ASAP..
1 2279How do we measure earth fault current in Generator Transformer(20/420kv),Station Transformer(20/11 kv) and Unit Transformers(20/11kv) for our plant system, since these don't have any Neutral earth Fault relay connected to their Neutral Earth? But for Unit Service transformers(11/.433 Kv) we have an Earth Fault Relay connected to its neutral earth.Why is such so?

1 4412A 230V dc shunt wound motor has an armature resistance of 0,15Ω.When operating on no load at 650 rev/min the armature current is 6A . The motor takes a full load current of 85A. Calculate the full load speed if the field flux is (i) maintained constant (ii)reduced by 0,03
