GGD Low-voltage switchgear assemblies

Overview

Since this device can effectively improve the power factor of the electrical load, reduce line losses, and enhance the actual load capacity oftransformers,it achieves significant energy-saving benefits.Additionally, by incorporating specific reactors into the system, it can efectively preventharmonic amplification and absorb the maiority of harmonic currents, ensuring that the total harmonic distortion rate and the content limits of eachharmonic current comply with national standards, thereby achieving the goal of harmonic mitigation, However, if ordinary contactors are used toswitch capacitor banks, this willresult in large inrush curents, slow compensation times, high maintenance costs, and a short service life. The reforewe recommend that users prioritize the use of dvnamic reactive power compensation devices in the following scenarios: substations, productiorworkshops, and low-voltage grids in civil buildings of industrial and mining enterprises, particularly in power distribution systems where loads frequently change and reactive power is unstable.

This product complies with the folowing standards: GB/T15576-2008 "Low-Voltage Complete Sets of Reactive Power Compensation Equipment'and lEC60439 “Low-Voltage Complete Sets of Switchgear and Control Gear."
