Method for determination of loss tangent and permittivity of electrical insulating materials in sheet form (Lynch method) Ingestion-build-146508 thus enhancing its service-lifeWhat is BS 4542 Lynch Method for finding of loss tangent and permittivity about? BS 4542 describes the Lynch method for the determination of the loss tangent and the permittivity of insulating materials at frequencies of 1 kHz to 100 kHz at normal room temperatures. BS 4542 gives details of the apparatus and of the procedure to be followed. The frequency range can be extended downward to 50 Hz unless the surface resistivity of the specimen is low (e.
