Large industrial facilities have their own medium and high voltage systems and many of them are connected to the Alberta Interconnected Electric System (AIES) at higher voltage levels than previously done. To ensure insulation system secure and reliable design and operation, insulation coordination should be evaluated, and high voltage transient studies be should performed where applicable. This presentation provides an introduction to aspects associated with performance of insulation coordination, selection and use of surge arrestors for the protection of electrical equipment, and applicable North America and International Standards. The presentation also touches on other high voltage transient studies such as breaker Transient Recovery Voltage (TRV) and fast and very fast voltage transients; when to perform them, and what is needed to perform them such as necessary equipment information and required software to perform the analysis.
