About 50 years have now passed since the time when mineral oil impregnated capacitors of high reliability became economically available, and during which power capacitors have undergone great strides of progress and advancement in dielectric properties, reliability, increase of capacitance, reduction of size and weight, etc. These owe much to the improvements and developments of dielectric materials and their applications, including improvement of insulating oils, development of new insulating oils, and introduction of polypropylene films. This paper presents topics in power capacitor advancement and a technical overview of power capacitors used today in Japan.
