Pollution Design & Monitoring of AIS Disconnectors Equipped with Porcelain Insulators
by Marco Nosilati

Porcelain continues to be largely used in AC substation disconnector support insulators and proper dimensioning is a fundamental challenge since correct design must be based on investigations to verify performance given different diameters and creepage factors at different altitudes. A real-time monitoring system also allows verifying anomalous conditions and optimizing preventative maintenance.
