Electrical properties of insulating materials

Electrical Insulation can be considered from at least three points of view: Theoretical consideration Engineering application Measurement All three are important and interrelated. Understandably an expert in each of the areas tends to emphasize his own points of view. In this tutorial session Dr. van Lint emphasizes the theoretical considerations in developing a model to describe radiation-induced conductivity in magnesium oxide. Ware deals with the properties of polyethylene which are important in its application as a cable dielectric. Dakin presents a very thorough discussion of corona measurement and its significance. Frisco describes the dielectric interrelationships between electrical components which affect both application and measurement.
