why it is in star to delta form of Synchrounus generator
and delta to star form of Generator Transformer (or step up
transformer)
Answer Posted / 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.....

HELLO EVERYONE, I RECENTLY HAVE FOUND ONE PROBLEM, I WAS TAKING NO LOAD TRIAL OF AN HT MOTOR 920 MOTOR , 1440 RPM , 6.6 KV, WITH AUTO TRANSFORMER. AT 450 V, LOAD WAS 40 AMP AND SPEED WAS 250 RPM. BUT AS WE INCREASE VOLTAGE FROM 450 TO 480V, LOAD BECOME 41 AND SPEED REDUCED TO SOME RPM . SO WHICH PHENOMENON ACTED HERE FOR REDUCING SPEED.?? AND IS IT HAPPENING ALWAYS OR IT IS RARE? I ALSO HAVE FACED SUCH PROBLEM WITH FEW LT MOTOR ALSO.
