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.
