Comparison of Spacefactor, Capacitance value and Impregnated Temperature in MPP Oil Impregnated Polypropylene Film A C Capacitors

Abstract

The MPP finished capacitors may be of dry type or oil type. This paper represents the testing and analysis of the impregnated oil MPP capacitors. The different dielectric oil is used to impregnate these capacitors. The palm oil, Olive oil, and sunflower oil are the three different dielectric liquids which are used as impregnated fluid. The electrical properties of all the oils are tested according to the liquid insulation standards. The capacitor considered for the test is a MPP capacitor single element and its value is 2.0μF/400V. The capacitor to be tested was impregnated at different temperature levels. From the test results, it is found that dielectric oil type, the treated temperature level and space factor affected to the value of capacitance.
