This text examines the influences of electric fields on dielectric materials and explores their distinctive behaviour through established principles of physics and engineering and literature on dielectrics. It aims to faciliate understanding of the space charge phenomena in the non-uniform fields and contains more than 800 display equations.

This publication discusses general problems related to the structure of current overload protection systems in high voltage (HV) electrical installations and introduces a family of new devices based on reed switch contacts, solid-state units, hybrid technology and automatic systems based on these components. It highlights their application in high voltage (5 to 100 kV) power supplies, power lasers and radar, RF-generators and protection systems for class 6 to 24 kV distribution networks.
