The fire hazard of large transition resistances. From theory to practice. Part 1

The statistics of fires at electric plants, broken down by the types of electric products, are considered. The need for a further search for technical solutions towards the protection of electric networks from large transient resistances is substantiated. Basic provisions of the contact theory are presented. The influence of various factors on the value of the transient resistance is shown. The generalization of theoretical data has been carried out, allowing to determine the ways of solving the problem under consideration.
