Farady Electric are top brand who is focus on power quality since 2006,we provide difference and customized solution for our client to improve their power quality and reduce their losses including AVR/SVC/SVG in difference area and application
++++Application
The distribution network system in urban and rural areas has long been faced with the problems of poor voltage quality, low power factor and large line loss due to the long power supply radius, strong load seasonality and other factors. Therefore, reducing losses and saving energy, improving the quality of distribution network power supply, and improving the economic benefits of power utility are urgent problems to be solved in the power system, as well as one of the main goals of Rural Electrification Agency in difference country

++++Working principle
Farady XBZW Type pole mounted MV static var compensator integrates voltage monitoring and reactive power compensation. It is a customized static var compensator developed to improve the situation of large inductive reactive power and high line loss of medium voltage overhead lines in power system.
It can be used to improve power factor, reduce line loss and improve voltage quality. According to the needs of the line, this SVC can control the voltage, time, voltage time, voltage reactive power or power factor (it can be changed according to the needs of users), and realize the automatic switching or fixing of parallel capacitors (according to the needs). At the same time, this SVC also has over-voltage, over-current, short circuit, quick break, under voltage, 10min delay, phase lose protection function.
This SVC is mainly composed of vacuum contactor, capacitor bank, controller, metal oxide arrester, current transformer, voltage transformer, mounting bracket and box.
For overhead line, the open type current transformer is used for sampling the current signal, and the device can be installed at the best installation point as lines needs.
For substation installation, it can gathering current signal and voltage signal from substation directly
