Answer Posted / muchha mondal
in online ups system has two bypass one is static bypass which is work automatically when inverter off or any fault in inverter ckt the load is transfer to static bypass without interrupted, and anather is manual or maintanance bypass.the maintanance bypass use only for maintanance purpase it should be always off when ups working normal condition.

I need the list of Universities who have summer intake for BS degree in Electrical Engineering.?
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.

A 100 kVA , 400 v/250 kv testing transformer has 8% leakage reactance and resistance on 100 KVA base . A cable has to be tested at 500 kv using the above transformer as a resonant transformer at 50 hz . if the charging current of the cable at 500 kv is 0.4 A find the series inductance required . Assume 2% resistance for the inductor to be used and the connecting leads . Neglect dielectric loss of hte cable . what will be the input voltage to the transformer ?
