Abstract :
This paper reviews the aging mechanisms and stresses that affect porcelain suspension-type insulators. Procedures and criteria for determining the overall condition of inservice porcelain suspension insulators on an aged line are described so that a decision can be made on their suitability for continued service or to replace the insulators.
