The role of harmonic protector

According to the market development needs Shanghai Kunyou Electric Co., Ltd. jointly with Shanghai University of Electric Power, research and development of a new generation of grid harmonic protector (KYXBQ), which can absorb a variety of frequencies, a variety of energy harmonic interference, harmonic elimination in the source of the occurrence of harmonic, automatic elimination of the power-using equipment generated by the random high harmonics and high-frequency noise, pulse spikes, surges and other interferences. Through this intelligent harmonic protector can purify the power supply, protect the power-using equipment and power factor compensation equipment, prevent the false tripping of the protection device, so as to protect the equipment to run safely and efficiently.
