This project was formulated with the objective of developing and documenting guides for selecting appropriately rated high-voltage metal oxide surge arresters, as well as for the preparation of the associated technical specifications.

Value to Electric Cooperatives

The need for such a guide is driven by the loss of expertise in developing equipment specifications as existing utility staff retires. Therefore, there is a need to transfer knowledge to new staff and also to document requirements on acquiring more reliable, safer and cost effective surge arrester technology for both new and replacement projects. The technical requirements covered include many normal utility requirements, operating conditions and applications for metal oxide surge arresters used on system voltage ratings ranging from 5kV to 800kV.
