How do you calculate a power rating for a capacitor bank?
For each step power rating (physical or electrical) to be provided in the capacitor bank, calculate the resonance harmonic orders: where S is the short-circuit power at the capacitor bank connection point, and Q is the power rating for the step concerned.
How to choose a capacitor?
Capacitors can be selected with their rated voltage corresponding to the network voltage. In order to accept system voltage fluctuations, capacitors are designed to sustain over-voltages equal to 1.1 times UN, 8h per 24h. This design margin allows operation on networks including voltage fluctuations and common disturbances.
How do you measure a capacitor bank?

Size the capacitor bank appropriately for its reactive energy compensation requirements, based on these measurements and your electricity bills.
