Answer / anwar hussain

Becoz the hv has high voltage but low current so for low current we need thin wire

Answer / t.r sharma

because if any fault is occurs in the system is more then its capacity system may be damaged so fuse capacity is lesser than system to protect them from fault or over voltage

Answer / koti1965

Because current is very low in HT.

Answer / khalaf

From the Ohm law, you make a low resistance by this thin wire to pass a high current that caused by the fault

Answer / maulik

in case of ht side the voltage is high so current is less and the fuse rating is depend on current so to carry low amount of current we require thin wire

Answer / mohd fazil

kyuki ht line ka amp. kam hota hai

Answer / adarsh gautam

transformer is in between ht line and system, which saves fuse to hold the load

sir , what happen if we decrease ( approx 3 inch ) the lenth of shaft in 110KW Induction , three phase motor. actually a 110KW motor is couppled with star couplling to 120TR compressor. When we doing maintenance in compressor it is required to skid the motor backword and resulting dis- alightnment . so we want to change the tyre coupling in place of existing coupling. so it is required to cut off the rotor aprox 3 inch form driving side.
