Abstract
This chapter is devoted to monitoring the condition of transformers, rotating machines and cables by the pulse method. The historical milestones in the development of the impulse method are described. The stages of modification of the technology of impulse diagnostics are given. The origin of frequency analysis as a development of impulse diagnostics is considered. New approaches to impulse diagnostics are explained. The possibilities of this method are illustrated by examples from the practice of diagnosing power transformers and rotating machines.
A significant part of the chapter is devoted to new diagnostic methods, which are still poorly covered in the literature. For this reason, the material is presented in sufficient detail.
