Introduction
Since this device can effectively improve the power factor of electrical loads, reduce line losses, and enhance the actual load capacity of transformers, it achieves significant energy-saving effects. Additionally, by using specific reactors in the system, it can effectively prevent harmonic amplification and absorb the majority of harmonic currents. This ensures that the total harmonic voltage distortion and the content of individual harmonic currents meet national standards, thereby achieving the goal of harmonic mitigation. In contrast, using ordinary contactors to switch capacitor banks would result in large inrush currents, slow compensation times, high maintenance costs, and short service life. Therefore, we recommend that users prioritize the use of dynamic reactive power compensation devices in the following scenarios: low-voltage power grids in substations, production workshops, and residential buildings of industrial and mining enterprises, especially in power distribution systems where the load frequently changes and the reactive power is unstable.
This product meets standards such as GB/T 15576-2008 Low Voltage Complete Reactive Power Compensation Equipment and IEC 60439 Low Voltage Complete Switchgears and Control Equipment.

Product characteristics
Inductive loads in power grids (such as generators, chokes, transformers, induction heaters, and welding machines) all generate varying degrees of electrical hysteresis, referred to as inductance. Inductive loads have the characteristic of maintaining the direction of current (e.g., positive) for a period of time even when the direction of voltage changes. Once there is a phase difference between current and voltage, reactive power is generated and fed back into the power grid. In an AC power grid (50/60Hz), the above process repeats 50 or 60 times per second. Therefore, an obvious solution is to directly use capacitors to temporarily store and release these inductive energies (reactive power), thereby reducing the reactive power exchange in the power grid.
