PISCATAWAY, N.J., USA, 6 March 2007 The IEEE has approved a new standard on electrical clearances and insulation levels at substations. It also has begun to work on an amendment to the standard on connections used in substation grounding standard and revisions to those for safety considerations for substation grounding and for the oil spills at substations.
The IEEE has approved IEEE 1427™, “Guide for Recommended Electrical Clearances and Insulation Levels in Air Insulated Electrical Power Substations”. This new standard, which covers three-phase ac systems from l to 800kV, develops guidelines for design, operating and safety clearances. It includes insulation coordination procedures and design procedures for selecting and coordinating the insulation levels for substation clearances.
IEEE has begun work on IEEE P837a™, “IEEE Standard for Qualifying Permanent Connections Used in Substation Grounding - Amendment”. This amendment will add specific electromagnetic force (EMF) testing criteria for grounding the connectors used to connect the ground grid to equipment and structures. Since no such testing criteria currently exist, methods and associated connectors used in grounding will be qualified through a test plan that simulates field conditions.
IEEE has begun to revise IEEE P80™, “Guide for Safety in AC Substation Grounding”, which is the main source for grounding information worldwide. This standard provides general and specific design information on grounding safety practices at power frequencies of 50 to 60 Hz at conventional and gas-insulated outdoor AC substations. The revision will include the addition of benchmark cases so users can verify their understanding of IEEE 80 equations and the limitations of these equations.
IEEE has begun to revise IEEE P980™, “Guide for Containment and Control of Oil Spills in Substations”, to update it to reflect the latest technological developments. IEEE 980 discusses oil spillage regulations and how they apply to substations, the sources of oil spills, typical designs and methods for dealing with containing and controlling spills, and guidelines for preparing a spill prevention control and countermeasure plan.
About the IEEE Standards Association
The IEEE Standards Association (IEEE-SA), a globally recognized standards-setting body, develops consensus standards through an open process that brings diverse parts of an industry together. These standards set specifications and procedures based on current scientific consensus. The IEEE-SA has a portfolio of more than 870 completed standards and more than 400 standards in development .
