Insulator Bushing Inspections 1

[CuriousElectron]

Greetings, all
Does anyone have technical references/guidance on how to inspect insulators(bushings) for damage or end of useful life, such as signs of pitting/arcing damage, etc. We'd need to evaluate pictures from the site to determine if replacements need to be ordered.
Thanks,
EE
