Some properties of castor oil affecting its performance as a capacitor impregnant and their significance to future impregnant research
Abstract
For a considerable time castor oil and polychlorinated biphenyl (PCB) were the principal impregnants used in energy-storage capacitors. Castor oil has proven to be better than PCB for pulsed applications. PCB's have come under attack as an environmental hazard, while castor oil is a vegetable product and its supply and quality are subject to fluctuation. These two facts make the development of new impregnants desirable. The properties of PCB as a capacitor impregnant are well known. A number of properties of castor oil and PCB's are compared. A comparison is made between the lives of castor oil capacitors and comparable PCB energy-storage capacitors. Some of the physical and chemical properties of castor oil which make it a good pulse capacitor impregnant are examined.
