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 correctly determined.
