FAQs about Steps for capacitor power outage operation
How many steps are required for a switched capacitor?
When switched capacitors are required, the minimum required number of stages must be specified, and if desired, the number of steps. If only the number of steps is specified, for example (3), one manufacturer may propose a (3) stage bank with 1:1:1 switching, the other may propose a less expensive (2) stage bank with 1:2 switching.

Should large capacitor banks be energized in incremental steps?
It is generally desirable to energize large capacitor banks in incremental steps due to system characteristics, tariff structure, and prospective voltage rise. As the number of switched stages increase, so does the cost of the equipment. For this reason, large capacitor banks are broken into stages that follow an incremental format.
How much does a capacitor bank cost?
The difference in list price between (2) stage and (3) stage capacitor banks in Table 1 is approximately $11,000. The cost difference for harmonic filters will be significantly more.

Can displacement power factor be corrected with capacitor banks?
Displacement power factor can be corrected with capacitor banks. Variable speed drives have different displacement power factor characteristics, depending on the type of rectifier. PWM type variable speed drives use a diode bridge rectifier and, have displacement power factors very close to unity.
Can a capacitor bank improve the power factor of a variable speed drive?
The true power factor can be improved substantially in this case through the application of input chokes or transformers which reduce current distortion. Capacitor banks provide no power factor improvement for this type of variable speed drives and can make the power factor worse by magnifying the harmonic levels.
