Because all types of loads required active power to do some useful work.and Apperent power is the total of active power and reactive power.it means apperent power can't be increase or decrease.so we have to limit the reactive power of the system so that we can use maximum active power. and we can supply the more power to the different loads.
THE MAIN FUNCTION OF THE REACTIVE POWER IS JUST TO PUSH THE ACTIVE POWER UP TO THE LOAD.SO JUST WE HAVE TO REQUIRED THAT MUCH RECTIVE POWER IN THE SYSTEM.

In Air circuit breaker LSIG protection unit is used. Without fault in cables (2 runs 3Cx150Sq.mm Copper, 1Kv grade, XPLE armored cable IR value is more than 550Mohm @ 500V Megger) and load section Long time Overcurrent protection is triggers and trips the unit. We changed LSIG protection with new factory tested unit. Even then fault is persisting. Please suggest the possible causes
