Ring main unit is to be used in CSS(11kva or 33kva) or PSS. it consists of three circuit breakers either it is vcb or depends upon design.it has a three ways one is for incoming remain two for outgoing.in this the connection of incoming and outgoing based upon the CT ratio.for selecting of CT'S is depends upon knee point voltage.

Can the output voltage of a rectifier be greater than the input AC voltage without the use of any voltage multiplier in the circuit??please provide the explanation too..

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.
