What happen if LV supply is fed to a HT motor?
Answer Posted / mahesh meshram
If HT motor fed on LT supply, motor will run slowly and speed will increase with time. Initially motor will draw app. 1/3rd of the rated current and it will also reduce by 2-5 amp and will get steady.Motor such type of performance is expected only if it's bearing, rotor and other factors are good.
