Pollution Design & On-Site Monitoring of Insulators for AIS Disconnectors

Porcelain insulators are still the main type used in AC substation disconnectors and their correct dimensioning is a fundamental challenge. Real-time monitoring allows verifying any anomalous conditions as well as optimizing preventative maintenance by performing remedial measures such as washing only when necessary. This presentation reports on indications for correct design of these insulators based on IEC 60815 specifications and provides results of laboratory testing to verify performance of disconnector support insulators of varying diameters and creepage factors at different altitudes above sea level
