Understanding & Mitigating Corona on Polymer Insulators by Jeff Butler

One of the factors affecting performance of network assets is electric field that can impact service life of transmission hardware and insulator assemblies, particularly polymeric types. Increased use of this technology means it is crucial to evaluate design and materials to mitigate any potentially damaging effects due to corona. This presentation will provide a better understanding of the phenomenon referred to as corona and how to evaluate the effectiveness of various solutions to mitigate its occurrence. It will also review the tools that are available to engineers to design transmission lines with suitable shielding to mitigate corona on polymer insulators and support the expected long-term performance of critical infrastructure.
