Load type: The vast majority of electrical equipment is nonlinear load. Among them, switching mode power supplies, computers, printers, copiers, TVs, elevators, energy-saving lamps, UPS, air conditioners, LED displays, etc., which are widely used, are the main harmonics and reactive power sources in the intelligent building power distribution system. Most of these devices have a small capacity, but a lot of them, and the overall impact on power quality is great. There are many single-phase equipment, and its electrical load accounts for about 70% of the total capacity. The use of single-phase power supply causes unbalanced three-phase distribution load, excessive current in the neutral line, and offset of the neutral point. The non-linear load has high harmonic content and low power factor.

Recommended solution: IVL-RCS static filter compensation component + IVL-APF active filter.

Recommended solution: In the low-voltage power distribution system, configure IVL-RCS static filter compensation components to compensate for reactive power, and configure IVL-APF active filters to filter out harmonics to achieve the best governance effect.
