Abstract:Electrical-engineering periclase powders (EPP) are used as high-temperature electrical insulating fillers in tubular electrical heating elements (TEH) and other electrical heating devices and equipment. When carrying out acceptance tests, the quality of EPP is evaluated according to GOST 13236-83 ['Electrical Engineering Periclase Powders. Specifications'].Until recently, in the Soviet practice, the electrical insulation properties of EPP have been evaluated on the basis of bulk resistivity and dielectric stre… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
