I need to compare the energy consumption of an industrial
machine before and after improving. Shall I compare the
apparent power or the active power? I know usually
factories use compensated capacitors (or other similar
components) to compensate the reactive power, so if I use
the apparent power, it's not the real power consumed.

Answer Posted / ullas
by connecting a capacitor bank to any inductive load meets
the reactive power demand. since the KVAR portion changes
the KVA portion also changes and KW portion remains i its
original position. since the factories are charged by the
electricity suppliers by considering in to their power
factor. whe we are having a low powerfactor, then reactive
demand is higher. so to meet this capacitors are used to
meet the reactive demand.

Why does the Solid state Rectifiers for 3-ph brake motors sometimes have 2 & sometimes 3 output terminals?
sir, 3phase induction motor takes different pf and different KW in three phase while running,explain reason
The power factor of the fixed load is 0.8, now the p.f is varying from 0.8 to 0.5.

Please help me regarding my one concern. - During earth pit testing we noticed that the Clean earth pit and dirty earth pit showing continuity (Resistance value - 5ohm) . I want to know that if both earth pit have separate location and there is not internal looping between PIT then why such continuity is showing on it . Because of this issue the field side all earthing point showing short. In PLC panel we are providing two types of earthing cable which is coming from separate earth pit (Clean and Dirty earth pit) because of earth PIT showing short our PLC is not complying spec . please help regarding this issues.
