Reactive power compensation is an important energy-saving device in modern electric furnace systems. The reliability of its operating performance is related to the safe and economical operation of the power grid and users. Its outstanding advantages are:

① Compared with medium-voltage and high-voltage compensation, short-network boost compensation has the effect of increasing furnace mouth voltage and furnace power, reducing short-network losses, and is of great help in increasing production.

② The use of high-quality high-voltage foil capacitors effectively controls the terminal voltage, making the entire device highly reliable and significantly reducing the operating costs of the device.

③ The capacity is adjusted by on-load voltage regulation using a special compensation boost transformer, so that the capacitor is no longer frequently automatically switched, improving the stability of the system.

④ The electrical protection system is comprehensive and easy to operate, ensuring the safe and reliable operation of the system.
