1. Overview of 7.94KV 500kVar High Voltage Shunt Capacitor 

High voltage shunt capacitor (Power capacitor) is mainly used in the A.C,Power system with 50Hz or 60Hz to improve power factor, reduce reactive power loss, mend voltage quality, plenitude elaborate generate power' equipment and supply power equipment efficiency, it is national recommend save power products.High-voltage capacitor refers to a type of capacitor consisting of a ceramic bushing, a capacitor element group, and a casing. High-voltage capacitors have the characteristics of low loss and light weight.

2. Function of 7.94KV 500kVar High Voltage Shunt Capacitor

       High voltage parallel capacitor is composed mainly of the packet, shell and insulation porcelain, the packet is connected in a particular way by dozens of components, separated by insulation and wrapped. The shell is welded with thin steel plate (or stainless steel plate),the two sides of the wall have the bracket for welding and installing. The lid of box is covered with (or embedded pressure assembly) line casing,components are made of polypropylene film and aluminum foil,and the capacitor is filled with excellent electrical insulation liquid impregnant.

3. Main features of 7.94KV 500kVar High Voltage Shunt Capacitor

Capacitors consume active power and release reactive power. They also present a low impedance to harmonics; in other words, they attract harmonic frequencies. Thus, they are installed in substations to:

- Correct power factor, consequently minimizes voltage drop at the load end, by injecting reactive volt-amp a.k.a. VARs.

- Minimize voltage fluctuations, typically generated near industrial facilities, using harmonic filter banks – improving power quality in the process.

- Capacitors are an integral piece of Flexible AC Transmission (FACT) device.


4. Working conditions of 7.94KV 500kVar High Voltage Shunt Capacitor
