Intelligent Power Capacitors
YD-8C
Integrated design, centralized reactive power compensation for power distribution system, local power factor correction for motor equipment, energy-saving system based on power factor correction
8C series intelligent power capacitor is a new generation of reactive power compensation equipment with high efficiency and energy saving, low line loss and improved power factor and power quality of 0.4kV low voltage power grid. It consists of intelligent measurement and control unit, zero-crossing switching unit, protection unit, two (△ type) or one (Y type) low voltage power capacitor. The bulky and bulky structural mode of the conventional reactive power compensation device has been changed. Therefore, the new generation of low-voltage reactive power compensation equipment has better compensation effect, smaller volume, lower power consumption, cheaper price, more cost saving, more flexible use, more convenient maintenance, longer service life and higher reliability. The characteristics are adapted to the higher requirements of modern smart grid for reactive power compensation.
