2429Off Load Tap changer generator Step-up Transformer, My question is, is safe to operate the tap say I want to change the tap position from 3 to 4, there is not load on the transformer but a 22000v 0r 1100 v is present on the secondary side from the common Bus *22000V/415 v
1 5539hi can you give any body fault level calculation, generator fault level calculation,transformer fault level calculation for system fault level with equation? i have 3.3kv generation voltage three gas gen sets, one is 1.9MW,2nd is 2.5MW,& 3rd is 3.8MW & i have 11 kv generation voltage one gas gen sets is 3.8MW, we are step up to 22kv by transformer
3 7952Acually generator neutral is earthed,if suppose cable from neutral is brokened under theearth ,what will happen.
L&T,
2 6937A.V.R maintains the voltage of a generator when it is in island mode but when the generator is synchronised with grid it maintenance the P.F,how it happens please any body explain it in detail.

Hello Friends I had my ONGC test today,but it was very bad.But I would give certain suggestions so that u may not face he problem which i had. Be thorough with Electrical Technology.Generators.motors stators etc.There are 5 questions on that. There were also good no.of questions from Hydraulic machine and Production technology. Then 3 from Strength of materials.And remember the dimensional quantities.
