An electrical capacitor is an electrical device that serves to store up electricity. It has various uses in electrical and electronic systems. It can serve as intermediate electrical energy storage to replace the batteries in any portable applications. These capacitors are designed using a number of different dielectrics. Dielectrics are the insulating materials between the capacitor films. In technical collaboration with conden-sateurs fribourg sa, switzerland, ctr manufacturing industry has launched mpp.Sh ac capicitor, specially designed for harmonic filtration at higher frequencies in ups and inverters.
