hw to find transformer is in normal position? whether its
in charged condition or not? except humming sound?

Answer Posted / bala123

Apart from Humming sound, we can found the following ways:-

1. OTI (Oil temperature indicator) shows the winding
temperature value
2.WTI (Winding temperature indicator)shows the winding
temperature value

but its not correct way because if we disconnect the TxR (after
some hours) charging both may show current values

Is This Answer Correct ?    1 Yes 1 No

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.
