BY REDUCING THE FREQUENCY

Answer / k.prakashchandra

You can not lower the load ,capacity, and voltage. To save
energy ,you are left with only reduction of line current to
lessen the I^2R losses.The pf of motor is highest at
full ,or nearly full load.At 35% load ,the pf is less and
hence, the line current is more than required to take the
load (HP)

Answer / maheshbabu calicut

by installing VFD(variable frequency drive)we can vary the speed of induction motors.at 35%load you can run the motor at low speed hence saving power

Answer / k.prakashchandra

Replace the motor with one of lower rating.

Just a silly question but just to make my curious mind bac to normal - Why was not 67 and 67N relays built into a single relay as i have noticed that the R,Y,B CT wiring end up into the 67 relay while the common of the R,Y,B CT wiring end up into the 67N relay. Then it was better if a single relay was manufactured just like the distance relay (21). Another question i would like to ask is - how do we know where the 67 and 67 N relay has to be placed.why is it not placed at the transformer bay? In the substaion that i am working -i have noticed that it is placed between a breaker and a common double bus bar and this line bay is connected to another substation at a remote place which is furthur connected to a load.
