In any practical applications, except three-phase load, there are a lot of single-phase load. Tree-phase compensation mainly resolved the problem of system three-phase imbalance, improving the compensation effect.

In common, three-phase compensation capacity has 20%-30% of total capacity. Every compensation loops are including 3 fuses, capacitor contactor, single-phase capacitor, single-phase reactor, those auto-recycle switching of loops are reflected by PFC regulator.
