by the way, my country is Turkey :)
Now a days in India, in Mumbai distribution APFC's are used to maintain P.F , in RSS depending upon the requirement capacitor banks are installed to improve the pf at transmission level. But due to some industries the power factor reduces which increases line current and some drop in voltage, depending upon the requirement they are charged and discharged. HT consumer's are penalized for the p.f if it goes below 0.98 and a compensation is given if thy maintain p.f more than 0.99.

1)Should we disconnect capacitor bank when powered by a generator?.
2)Can somebody give ratings of capacitors for starting(reducing starting current) induction motors for various sizes of motors(hp/rpm)?.
3)Can somebody give ratings of capacitors for pfc of individual motors of different hp/rpm
Thanks2011/01/13 at 5:24 pm #11732AnonymousGuest
By the rules in Brazil, users supplied at voltages greater that 2.3 kV (group A) must have their PF verified by the utility in a mandatory and permanent way (art. 34, reg. 456/00). Users supplied at voltage lower than 2,3 kV (group B) can measure their PF in a facultative way. If that PF is lower than 0.92 (inductive or capacitive), reactive energy consumption and demand are mesure and charges apply (Art. 49, reg. 456/00). Furthermore, according to art. 68, reg. 456, users from group B can be charged by their reactive energy and demand, if their PF is lower than 0,92 during a minimum period of 7 days. From my point of view, if utilities adopt electronic meters to also register the PF of residential users, there are no regulation that don’t allow them to charge us by the reactive energy. So, the end is near… Are you agree?2011/01/15 at 12:31 pm #11736
Can any one on the list inform me correct connection of Power factor capasitors to be installed after the Electricity meter or else on the bus bar.

In Srilanka no penaly or any surcharge for power Lag.

I just know that Power Factor Correction policy in some countries much higher than in Indonesia.
Very good for optimization of generator utilization..2011/02/04 at 9:29 am #11800Dragos CoditaParticipant
I am from Romania. I am not aware of penalties applied at least to home consumers. I have no connections to industrial world, so i don’t know what’s up there.
It would be usefull to know the source of this informations.2011/02/17 at 2:25 pm #11828AnonymousGuest
Thanks for this information. We work with electric utilities, major corporations, government agencies, and equipment manufacturers around the world. PF correction is a topic of rising interest, so thanks for providing this helpful information2011/02/27 at 6:01 am #11856Horst DroegeParticipant

can anybody please direct me to where i can get standard power factors of various equipment for a hospital? ( example motors,elevators,pumps,refrigirator,medical equipment,kitchen equipment,low current equipment…..2011/04/23 at 7:22 am #12005
I'm Cambodian, I working in Electrical of Cambodia. It is very very important for me about information from neighboring country or worl wide, the formular (or policy) for penalty to the costumers that utilize more reactive energy per month over admisible. Thank for your good ideal. Please sent to firstname.lastname@example.org/04/25 at 6:35 am #12014
it is nice information about PF. thanks
thank sir i get lot of information about the P.F2011/04/26 at 9:59 am #12015

Hi, this is amit kulkarni fm Ahmednagar,maharashtra india,
i do energy audit in various sector such as foundries, cnc shops,machine shops,forging,colleges etc.
power factor =Real power/active power.
to calculate origional PF
u require some data like
1.consumption of instrument in kwh (Ew)
2.consumption of reactive energy in kvarh (Eb)
also u must know hp of insrument,rpm,efficiency.
Active energy power (P) = Ew/t.
origional pf = 1/√(Eb/Ew)+1 .2011/05/16 at 6:21 am #12082paukkyaingParticipant
I am from Myanmar, one of LDCs in the world. Although our country is over 50 times larger than singapore, our power consumption is only 1/10 times of Singapore. I mean Myanmar power system is not big. Our country has no penalty for power factor lagging. But now a day, we have problems concerning with power factor improvement. And also have problems in voltage and frequency control. Many of substations in our country did not have capacitor banks or shunt reactor before 2009. I would like to know that is there any relation between PFC and voltage and frequency control? Please anybody answer.2011/05/25 at 11:26 am #12099AnonymousGuest
1.u should disconnect capacitors b4 starting genset.
capacitor acts as load on generator.
2. there are various types of capacitors like MPP, Gas filled etc. depending on the working of motor one can suggest u the exact capacitors.
if u need mail me on email@example.com
