Power factor in 2016

POWER FACTOR :

                                                  simply power factor means the ratio between real power(KW) and apparent power(KVA),then power factor angle means angle between supplied voltage and current mentioned by COS angle.

POWER FACTOR ANGLE :


                               The above diagram is the power factor triangle,then its clearly explained by power factor  meaning,so kindly refer once.


POWER FACTOR TYPES :

                                                                       A.Lagging power factor 
                                                                       B.Leading power factor
                                                                       C.Unity power factor

WHY WE NEED TO KNOW P.F :

                                                                                         power factor is very important for big industrial because of they are not maintained p.f then getting penalty form government.How its happened in low p.f  because of in industrials have many of electrical motor,welding machines,transformers and induction furnaces may be these are the machines have low power factor that's why low p.f occurred so we need to cancel that low power factor others wise be ready to pay penalty.

How to charge electrical bill in government =Fixed charge+low power factor charge+volume charge

so we need maintain zero for low power factor charges that's why we need to know power factor.

POWER FACTOR FORMULA :



POWER FACTOR IN (V&I) :








power factor is mentioned in cosine angle between supplied voltage and current 
The above diagram is power factor correction diagram

POWER FACTOR CORRECTION :


                                                                              1.capacitor bank
                                                                              2. synchronous condenser 
                                                                              3.phase shift method 


SIMPLE CAPACITOR BANK DIAGRAM:

Material required for capacitor bank

1.Isolator 
2. contactor
3.fuse base and link
4.fan
5.capacitors
(note-all the items ratings based on MDB and demands )
