Capacitor compensation cabinets can effectively improve the power factor of the power grid, save energy, and improve power supply quality. Power factor refers to the percentage of apparent power in a power grid that is used to supply active power. In the operation of a power grid, a higher power factor is desirable. If this is achieved, most of the apparent power in the circuit will be used to sup...
