Power quality is an index system that measures whether consumers use electricity to cause pollution to the power grid. It directly affects the safety, reliability, and economics of both power suppliers and consumers. The main factors affecting power quality are harmonics, reactive power, three-phase imbalance, voltage fluctuations, and flicker. Power filtering technology and power factor correction technology have created conditions for improving power quality, saving user investment and ensuring rapid return on investment.
For ordinary loads, the anti-resonant reactive power compensation management of contactor switching is adopted. For the fast and convenient loads, the anti-harmonic reactive power compensation management of thyristor switching is adopted. For the loads with harmonics and fast transients, TSVG or TAPF。

Harmonic protector
.
LDHR type harmonic protector has a strong ability to eliminate the harmonic interference of various frequencies and various loads. It has a wide application frequency band and shows high response speed and instantaneous elimination in anti-surge and instantaneous pulses. These characteristics of frequency noise and instantaneous interference are suitable for non-linear load occasions such as various high-tech equipment, pipeline automatic control systems, large-scale computer network systems, digital signal processing and switching and control systems.
