what happen when dc shunt motor field is sudden open in
running condition
Answer Posted / tarak
the flux becomes very less dat is only residual
magnetism.as speedinversly proportional to flux d speed
will become very high.

Why is a plain induction motor unsuitable for wide speed control?
what do you mean by every IC 74 first digit.why are you using this no.why not using another no.
3 shows a 415 V, 3-phase generator supplying a 3-phase 415/110 V transformer. Draw the individual and combined impedance diagrams to a base of 10 kVA. Determine the system fault kVA and the fault currents at the 415 V and 110 V busbars for short circuit faults on the transformer input or output terminals. Work in p.u. values of impedances.
