Porcelain insulation – defining the underlying mechanism of failure

Porcelain insulation – defining the underlying mechanism of failure

Porcelain insulators have a long history and wide application range in power systems, but just like any other insulator, they can fail. A number of pole fires occurred on lines utilising porcelain suspension insulators. In some cases, the insulators appeared to be visually intact with no external si...
