What is the different between HT and LT Motors

 HT Motor - High tension (Voltage ) motors 

    HT motor called high tension motor usually supply above 1.1 kv and its rating mostly above 150 KW

The increase in voltage leads to decrease in current which there3by leads to decrease in size of conductor. Thus the size of cables and transmission line deduces. The protection equipment required for the same also reduces. Also the size of machine reduces as compare to that of LT Motor size.

LT Motor - Low Tension (Voltage) Motors

     LT motor called low tension motor usually supply from 230V single phase and 440v 3 phase system. It’s rating less than 150 kW.
