Capacitor banks are used to control the power factor in a power system. By connecting suitable capacitors the power factor can be controlled / maintained at a desired level. The requirement of a capacitor changes as the load changes dynamically. The same amount of capacitors can not maintain the desired power factor all the time. To be able to connect only the required number of capacitors, multiple (bank of capacitors) capacitors are included in a system. An automatic controller senses the actual power factor and connects and disconnects the capacitors from the bank as required

What is the functions of ceramic capacitor?
Ceramic capacitors can be used anywhere a capacitor having very low internal parasitic inductance is required. Most commonly they are used as powersupply bypass capacitors. They are also sometimes used for coupling capacitors for HF signal amplifiers.
How do you identify that capacitor is as Electrolytic capacitor?
Electrolytic capacitors look like little batteries. Any capacitor that looks like this will be electrolytic.Another AnswerElectrolytic capacitors are polarised, so their terminals are marked with positive and negative symbols.
Define mica capacitor?
A mica capacitor is simply one that uses the mineral mica as the dielectric or insulator between plates.
Is capacitor polarity sensitive?
Some capacitors are polarity sensitive; some are not. It depends on the design. Electrolytic capacitors, for instance, are polarity sensitive, while ceramic disc capacitors are not. You can generally tell, if the capacitor is marked with polarity signs, such as + and -, if it is or not.
What is difference between variable capacitor and fixed capacitor?
variable capacitors are those capacitors which can be intially or randomly canged by the user for example radio tunning.whereas fixed capacitors are those whose value is fixed and can't be changed. sohaib
How Capacitor Banks works in Electrical System?
Capacitors used in delta connections so that they increase the power factor
What is an unpolarized capacitor?
A capacitor that does not have a designated + and - side. Electrolytic capacitors are usually polarized. Ceramic capacitors are not.
What are the different types of capacitors?
Ceramic capacitors, film capacitors, multi-layers ceramic capacitors, electrolytic capacitors, mica capacitors, super capacitors, etc. -- We're JYH HSU(JEC) Electronics Ltd (or Dongguan Zhixu Electronic Co., Ltd.), an electronic components manufacturer.

Why Capacitor bank should be switched off when DG is in operation?
When generation kicks on, it can cause system voltage to rise, fall, or stay the same. Capacitors banks are used to help boost system voltage. Inductor banks are used to pull system voltage down. In many situations, capacitor banks may be required to kick ON when generation kicks on - some wind turbines "suck in VARS", or act like inductors while pushing out power. This causes system voltage to sink, and must be counteracted using capacitors. In your situation the distributed generation may be causing unacceptable voltage increases with the capacitor bank online.
How capacitor rated?
Capacitors are rated in Microfarads
The air conditioning work in 230 volt why the compressor use capacitors of 370 and 440 volts if he only need mfd to start?
An AC capacitor is composed of two DC capacitors with the foil ends (-) connected together and the center ends (+) connected to the outside. There are variations to the connections. Each capacitor has to have the voltage rating required by the application -- and there are two capacitors in series in an AC capacitor. A 230V AC capacitor, depending on manufacturing design standard, may not be suitable for starting a 230V air conditioner.

What is coupled capacitor?
There is no coupled capacitor in existence that i know. Capacitors can be used to couple or decouple a signal
What size capacitor?
Capacitors come in various sizes, your question is to non specific (capacitor for WHAT) for a detailed answer.
Function of dielectric in a capacitor?
The main role of dielectrics in capacitors is to increase the value of capacitance of the capacitor.
What is junction capacitor in integrated capacitors?
reverse biased PN junction MOS capacitors are more common
