Advantages of Power Factor Correction :
- Avoid p.f. penalty imposed by electricity board due to poor power factor.
- Reduction of M.D. (KVA demand), thereby reduced bill and increased capacity.
- Awail p.f. rebate on demand & energy charges in elect bill upto 7.5 %.
- Reduced load current, distribution losses, heating of transformers & cables.
- Increased service life of all electrical equipments in the plant.
- Shortest payback period on investment – from 2 to 18 months.
|
Advantages of Harmonic filtering :
-
Reduction in overheating of transformers (k-factor), switchgears,motors and cables
- Reduction in failure of PFC capacitors, PLCs, motors, transformers and cables
- Lesser current in neutral conductors
- Prevention of mal-operation of electronic equipments and cards
- No errors in energy meters, counters, PLCs and other sensitive equipments
- No production downtime, thus increased profitability for the industry
- Avoid nuisance tripping of breakers, fuses and protection relays.
