As this device can effectively improve the power factor of electrical loads, reduce line losses, and increase 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 effectively absorb most harmonic currents, bringing the total harmonic voltage distortion limit and individual harmonic current content limits into compliance with national standards, thereby achieving harmonic mitigation. If ordinary contactors are used to switch capacitor banks, the result will be large inrush currents, slow compensation time, high maintenance costs, and short service life. Therefore, we recommend that users give priority to the use of dynamic reactive power compensation devices in the following applications: low-voltage power grids such as substations, production workshops in industrial and mining enterprises, and civil buildings, particularly in power transmission and distribution systems where loads frequently change and reactive power is unstable.
