The fire hazard of large transition resistances. From theory to practice. Part 2

The author addresses various types of contact joints and methods of preventing the emergence of large transient resistances on them. The article has guidelines governing regular preventive repair works aimed at the maintenance of contact points. The analysis of various technical solutions for the protection of power grids from high transient resistances has been conducted. The author demonstrates methods used to control and monitor the condition of potentially dangerous contact sections of a power grid. The author makes recommendations on the joint application of management actions and technical facilities to address fire safety issues of electrical installations of buildings.
