Answer / suhas

after generating voltage, it has to be transmitted....to
transmit we use delta connection as it needs only 3 wires
which saves money...steppin up of voltage is done to
decrease losses in transmission...so step up transformer
has Y-del connection...in the receiving end(step down) we
can use del-del or del-Y...by using del-Y connection we hv
d flexibility of selecting the 3 phase and 1 phase
voltage... this method is done usually for
distribution...for further transmisssion, in swithing sub
stations, the step down trafo will be del-del....with
tertiary as star.....

Ceiling fan motor wiring Hi, I have 2 ceiling fans broken. The receiver/control units burned out due to lightening. One Harbor Breeze and one Hunter's I took them apart (remove receiver units). Now on both of the motor I see 4 wires coming out from each motor I really want to know the function of each wire. Are there anyway I can test to see which is which? After searching forums I know these 4 wires are from 2 sets of coils inside the motor, one is Start winding and the other is Runing winding I could not find the receiver/control unit any where, so I am planing to buy Capacitors and universal remote controls to make the fans run again. Anyone has any idea how to do the wiring, please help Thnks

is KVAR (not reverse power) relay necessary to protect from excitor field failure on a brushless, synchroneus generator? Some people with previos experince tell me no but the manufacturers tell me it is designed for that purpose. Is it that it is only necessary for brushless generators and not the older style with the slip rings and brushes?
