Dingfeng Capacitor-------What is a Capacitor Bank and Why is it Used

In simple terms capacitor banks are collection of capacitors connected together in series or parallel depending upon requirement.
They are primarily used for compensating electrical power system , mainly to regulate Reactive power. In an AC electrical system there are three kinds of power viz. Active , Reactive and Real power. 
There is term called power factor(P.f)
    P.F.=                Real power ________  
             Apparent power(Active + reactive)


In order to have an efficient power system , and to maintain the transmission voltage profile within the prescribed limit , we need to keep power factor close to 1.
Regulation of Reactive power or P.F  is achieved by absorbing or releasing leading and lagging VARs. which is done by Capacitor banks and Inductors.
Reactive power is mainly required for magnetization of Inductive load (transformers, induction motors , lightning equipment etc) . 
There is a time in a day when demand for reactive power is really high , like in morning when Industries start or in evening when everybody light up their bulb . The demand exceeds ,the reactive power available in the system . To supply this excess demand of reactive power , we need Capacitor bank or synchronous motors or other methods of compensation.
Similarly at times ,amount of reactive power in a system is greater than the requirement , in such a case Inductors are used to absorb extra reactive power.

As one of the earliest capacitor manufacturers engaged in producing capacitor for over 28 years in china , we believe one day Dingfeng Capacitor will exist in every corner of the world by means of its reliable quality and good reputation. By the way,Dingfeng sincerely welcomes all the friend to visit our company and hopes to have a good communication and double-win partnership with all of you cause dingfeng capacitor is always on the way to be better! Your views are the driving forces of DingfengI hereby on behalf of all the members of Dingfeng, thank all of you for the long-term supporting and concerning of our growth.
