Physical Conditions of Electrical Equipment

Testing, Monitoring, and Diagnostics

Equipment reliability might be significantly improved through the effective prediction of equipment degradation. To evaluate the degree to which an electrical machine has degraded, it is necessary that one is able to measure the values of the most important physical parameters characterizing a specific condition. For electrical apparatus there are multiple parameters that are directly related to the performance of the machine.

In this chapter, the main focus is on the physical conditions of the materials that the components of electrical equipment are made of. The electrical equipment include HV and MV electrical equipment, such as gas-insulated switchgear ...
