Dear Sir , if u can offer comments on method of connection of capacitor banks i.
Hi, I just came by to learn about this place. It seems to be really full of great content and I had a good time viewing it, thank you very much for the good article! I am looking for an experienced designer to design a KVAR automatic power factor correction system for residential applications as well as a similar system for commercial applications KVAR.
Systems will have optional harmonic filters typical to each environment. Hi i m electrical service engg makes n repair power factors. Expecting an article on harmonic filters, applications, connections etc and also difference between harmonic filter and APFC. Sir, We are maintaining power factor of 0. Kindly suggest the same. Sir, When the apfc panel will compensate the inductive load and capacitive load. The leading PF or over compensation may result in high Harmonic Resonance, Switching Spikes, Overvoltage, tripping of protection relays, and other undesirable local effects for your installation, the local Supply Network, and your nearby neighbours in the Supply Network.
Please help. Please guide on this? I have a query if there is unbalanced condition e. DG is also beside the substation.
Recently i found one problem at site…we have KVAr cap. I was searching something related to electrical equipment Servo Stabilizer on the google, i found your blog there, i read it and find so many things important, i appreciate to writer for such information, thanks a lot. If you have any suggestion or solution kindly share. Sir we have installed kva apfc with 6. I will reduce the cost as HT capacitors are more costlier than LT.
Please suggest…. Hi I have a query about the manual operated capacitor panel. At one place this manually operated PFC device is installed but still it is recording low PF by the utility meter. This is a booster pumping station which operates 8 hr a day on an average. Pl reply. Al this conversation is very useful and practical. Hope all will improve their knowledge. Deepak sharma.
A 1, KVA transformer with an 0. If I connect a household energy meter to its terminals and turn it on for 1 hour How much the energy meter will read??
Is it KWh?? Please check. I am doing B. We have a situation where we have installed a solar grid tie system in a factory which has an existing APFC. The average pf before was. Is the only solution to add capacitor bank? What happens when solar generation comes down if capacitor bank is increased? How to compute electricity billing in case of PFC breakdown? Let say the breakdown period is 10 days.
Evidently the meter will registered poor power factor during that period. Appreciate your efforts in explaining the power factor correction in such comprehensive fashion. Thanks for this article. Sir, what is the size of cable to be connected in kvar apfc panel which is having reactor?
All the allied Panels used to control the crane movement are designed for Volts rated only like Panel,Switchgear,Busbars etc. Kindly suggest us if possible with calculations the rated voltage of Capacitors to be used? Hi Sir, What happens when a manual operated capacitor bank is connected at NO load condition?? Dear Sir, Thanks for to give usefull knowledge. Sir I want to know that how to decide quantities and rating of capacitors in apfc panel designing.
Suppose I want to design a 90 kvar apfc panel than how many and which rating capacitors should I used. Kindly suggest. Our head office has a problem with voltage imbalances. This is caused when some of the lighting points are switched off in the evening.
We are metered on three phase v. Please assist. Dear sir, Me, Mr Ajas, working as electrical engineer in saudi arabia. Can you guide me how to calculate capacitor bank easily. I have done my voltage drop calculation and cable selection. Following Data with me: Connected load and demand load demand factors up to substation ampacity of cable and voltage drop.
As present the power factor of auxiliary supply at our site ranges from 0. This indicates there is a scope for power factor improvement by reactive power compensation. Conditions with power factor 0. Can you suggest what type and rating capacitor bank is mostly suitable for us??
This wa really helpful… Sir i have this as my FYP final year project … can you help me with the proposal? Does APFC panel work if current is in the reverse direction if we are feeding solar power in the grid via transformer? Dear Sir, Kindly tell us how to divide capacitor bank in stages and rating of capacitor of each stage.
Hi, very nice in informative. I need your help. Hi, My i have selected kVAR capacitor panel, but how to calculate the input current of capacitor panel from my LT swgr panel.
Sir, can overcompensation of capacitor banks cause circulating currents at the terminals of HT motor? How to measure Line voltage by using any instrument in a three phase supply? That may be any circuit by which we can measure Line voltage between any two phase, help me by giving that circuit.
It has taken leading units of KVAr in the formula. So please guide us. But in no load time we are facing leading power factor Is there any automatic controller to maintain the pf. I was repeatedly doing some mistakes in making of my panels your article and the comments helped me with my doubts. You are commenting using your WordPress.
