GGJ Low-voltage reactive power inteligent compensation device

The GGJ low-voltage reactive power intelligent compensation device can effectively improve the power factor of the electrical load, reduce line losses, enhance the actual load capacity of the transformer, and has significant energy-saving effects. At the same time, by using specific reactors in the system, it can effectively prevent harmonic amplification and effectively absorb most harmonic currents, ensuring that the total harmonic distortion limit and the content limit of each harmonic current comply with national standards, achieving the purpose of harmonic control. However, if ordinary contactors are used to switch the capacitor bank, it will result in large surge currents, slow compensation time, high maintenance costs, and short service life. Therefore, we recommend that users give priority consideration to using dynamic reactive power compensation devices in the following scenarios: power plants and workshops of industrial and mining enterprises, civil buildings, etc. of the low-voltage power grid. It is particularly suitable for power distribution systems with frequently changing loads and unstable reactive power.

This product complies with: GB/T15576-2008 "Low-voltage integrated reactive power compensation equipment", IEC60439 "Low-voltage integrated switchgear and control equipment", etc. standards.
