12. PESHAWAR ELECTRIC SUPPLY COMPANY RTC PESCO CHARSADDA ADVANTAGES The reduction of reactive current results in a reduced total current. Which in turn causes less power losses. The power factor correction produce economic saving in capital expenditure and fuel expenses through a release of kilo volt ampere capacity and reduction of power losses in all the apparatus between the point of installation of capacitor and source power plants including distribution lines, sub station transformers and transmission lines.

14. PESHAWAR ELECTRIC SUPPLY COMPANY RTC PESCO CHARSADDA Capacitor Rating In KVAR Kilo Volt Ampere R eactive

15. Fixed Capacitor Bank Installed a fixed quality of kVAR electrically connected at one or more locations in the electrical distribution systems. When the system is lightly loaded, and the amount of kVAR energized is too large, the voltage can be so great that motors, lamps, and controls can burn out. It is a important fact to remember that kVAR equal to 20% of the transformer kVA is the maximum size of a fixed kVAR bank. Valued greater than this can result in a large resonant current, which is potentially harmful to the system.
