Discussion on “an overpotential test for insulators” [PDF]
Journal of the American Institute of Electrical Engineers, 1922 C. E. Skinner: Porcelain is essentially in effect a conglomerate of spar, flint and kaolin. Each individual piece has its own personal history. A very large number of factors inevitably enter in, to affect it for good or ill in its making. Much can be done by the ceramist and by the porcelain factory to insure uniformity, but the day will never dawn ...

A New Current Transducer for On-Line Monitoring of Leakage Current on HV Insulator Strings
IEEE Access, 2022 Leakage current measurement and its harmonics have been widely used for the pollution level estimation of HV insulator strings. However, the solutions available to applications into transmission lines and substations are few and it reduces the creepage ...

Analysis of the Influence of Silicone Rubber Aging on the Transmission Parameters of Terahertz Waves
Energies, 2021 In this study, a method for testing the aging of silicone rubber insulators using terahertz waves in the 0.17–0.22 THz frequency band is proposed, aiming at the problem of online non-destructive testing of the aging degree of composite insulators.
