WG Draft Guide for the Application of Surge Protective Devices for the Smart Grid

Low Voltage Working Group Titles and Scopes IEEE/PES/SPDC Subcommittee 3.6 Low Voltage Surge Protective Devices Smart Grid Surge Protection Guide Working Group Chair: Matt Wakeham Provide surge protection guidance for electrical equipment and systems with voltages of 1000 V (ac) and 1500 V (dc) or less for components of the Smart Grid. Included within this scope are communications and data acquisition equipment and associated circuitry and interfaces. Additionally, there are cases which involve smart grid equipment attaching or coupling to higher voltage circuits such as electric utility medium voltage distribution. This scope does not limit providing guidance for such matters. The High Voltage Subcommittee Chair has approved this scope in the A&S Committee meeting. This working group is a combined effort of both Low Voltage and High Voltage members.
