KVA=KW/Power fector

Answer / birinchi87

KVA is the Apparent Power rating which has two components: one is Active and another is Reactive. And KW is the Active Power rating. KW depends upon load power factor. Generally electrical equipments like Transformer are rated in KVA because KW is not constant. It depends on power factor but KVA doesn't depend on Load power factor.
KW/KVA=cos(phi)=power factor

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

For a 6.6kV Motor it is recommended to do megger test with 500 V d.c and not more than 5kV d.c but the Hi voltage withstand test should be performed by 12kV AC. Why the dc voltage test should be limited but AC voltage withstand test could be with such a high voltage?
