8.2: Capacitance and Capacitors

Multiple capacitors placed in series and/or parallel do not behave in the same manner as resistors. Placing capacitors in parallel increases overall plate area, and thus increases capacitance, as indicated by Equation ref{8.4}. Therefore capacitors in parallel add in value, behaving like resistors in series. In contrast, when capacitors are

Capacitor Bank: Definition, Uses and Benefits

A capacitor bank is a group of several capacitors of the same rating that are connected in series or parallel to store electrical energy in an electric power system.Capacitors are devices that can store electric charge by creating an electric field between two metal plates separated by an insulating material. Capacitor banks are used for various purposes, such as

Point-on-Wave Capacitor Bank Switching

a capacitor bank is de-energised a residual DC voltage will be left on the capacitors. This commonly means there must be a 6-10 minute delay period while the voltage decays before the bank can be re-energised. When switching capacitors, inrush current occurs when there is a rapid change of voltage across the capacitors. The theory of Point-on-Wave switching applied to

6 FAQs about [How to write an analysis for a capacitor bank]

What are the underlying equations of a capacitor bank?

Because capacitor bank equations are linear and there is no mutual coupling inside the bank, the underlying equations for the calculations are simple: the unit reactance ties the unit voltage and current while Kirchhoff’s laws tie all voltages and currents inside the bank. However, solving these underlying equations by hand is tedious.

What are the requirements for a capacitor bank?

EN 61921:2005 describes the general requirements for the capacitor bank. The most important of them are listed below: Index of protection depends of the place of the installation of a capacitor bank. If the capacitor bank is to be placed in the same place as the main switchgear or utility room next to it, IP 20 is enough.

What are the different types of test performed on capacitor banks?

There are three types of test performed on capacitor banks. They are Design Tests or Type Tests. Production Test or Routine Tests. Field Tests or Pre commissioning Tests. When a new design of power capacitor is launched by a manufacturer, it to be tested whether the new batch of capacitor comply the standard or not.

What factors should be considered when designing a capacitor bank?

When designing a capacitor bank, many factors must be taken into consideration: rated voltage, kvar needs, system protection and communications, footprint and more. These factors govern the selection of the capacitor units to be used, along with proper grouping of these units.

When a capacitor bank is installed at site?

When a capacitor bank is practically installed at site, there must be some specific tests to be performed to ensure the connection of each unit and the bank as a whole are in order and as per specifications.

What is the detuning factor of a capacitor bank?

Since the detuning factor for the project was given as p=7%, one knows that the capacitor bank needs to be equipped with reactors. For this reason, some calculations have to be performed, in order to fit the power of the capacitors and its rated voltage taking into account reactive power of a detuning reactors.
