The capacitor bank is connected upstream of the HV/lV transformer. The additional cost connected with high voltage insulation rules out any benefit of using this for low power compensation (apart from in the case of individual requirements).
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.
The impedance for a circuit with a power factor compensation capacitor is given by Equation 5, where XC is capacitive reactance and is given by Equation 6. In most industries, a system of capacitors controlled by a power factor correction controller is installed for reactive power compensation.
At low voltage, compensation is provided by: Note: When the installed reactive power of compensation exceeds 800 kvar, and the load is continuous and stable, it is often found to be economically advantageous to install capacitor banks at the medium voltage level. (see Fig. L11)
This installation type assumes one capacitors compensating device for the all feeders inside power substation. This solution minimize total reactive power to be installed and power factor can be maintained at the same level with the use of automatic regulation what makes the power factor close to the desired one.
This type of compensation method demands capacitor banks to have wide range of power regulation, which can be determined by 24h measurements at the place of installation of the circuit breaker. What’s good in this solution // But, the downsides are : The losses in the cables (RI 2) are not reduced.
Compensation capacitors can be added for filtering effects. The compensation capacitor may be used to reduce bandwidth, for example in a case where that signal frequency is not needed and the designer wishes to reduce noise.
