The difference between single-phase capacitors and three-phase capacitors

1. Single-phase capacitors are common single two-wire capacitors. Three-phase capacitors consist of three common single two-terminal capacitors, which are Y-shaped or delta-shaped.

2. Three-phase capacitors mostly only suppress harmonics, and single-phase capacitors are truly accurate.

3. Both require different controllers to work with. Three-phase load balancing can be done in three phases or in three single phases. The load is heavily unbalanced and requires single-phase capacitance for single-phase compensation.

4. Under normal circumstances, the three-phase capacitor is a star connection method. When used in the compensation of reactive power compensation, the single-phase capacitor is connected in a delta connection, and the single-phase capacitor has a stronger suppression of harmonic generation.
