What is a Capacitor Bank?
Capacitor banks act as a source of local reactive power and thus less reactive power flow through the line. By using a capacitor bank, the power factor can be maintained near to unity. Improving power factor is the process of reducing the phase difference between voltage and current.
Capacitor bank selection
Any technician with minimum electrical knowledge can determine or calculate reactive power compensation. The most common practice is using "a single" electricity bill. The emphasis here is on the "single" electricity bill as it is precisely here that a series of errors can start, which can often end up, with higher costs than those involved when a capacitor bank is …
