The phase split compensation power capacitor will be drawn from the contents of the public line, and realize the single multi way connection. Its structure is reasonable, the installation is simple, safe and reliable, and over current capability is better. In philosophy, with a single power capacitor star connection leads to (neutral line or not connected to the neutral line), single-phase multiterminal leads. Meet the needs of the user three-phase total complement, sub complement, composite fill and so on.
