IEEE approves new standard for reclosing line circuit breakers on transmission/distribution lines

PISCATAWAY, N.J., October 9, 2002 — The Institute of Electrical and Electronics Engineers Standards Association (IEEE-SA) Standards Board has approved a new standard for automatically reclosing line circuit breakers on transmission and distribution (T&D) lines.

It also approved the start of work on two other T&D standards: a new guide to protective relay applications and the revision of a standard on lightning performance. A new standard that will compare distribution equipment in North America and Europe was also begun.

The new standard, IEEE C37.104 â„-, “Guide for Automatic Reclosing of Line Circuit Breakers for AC Distribution and Transmission Lines,” describes current practices for automatically reclosing transmission and distribution lines, as well as reclosing considerations and coordination practices.

The three projects begun involve two new standards and the revision of an existing standard:

? IEEE PC37.230 â„-, “Guide for Protective Relay Applications to North American Distribution Lines,” will be a new standard on how to protect power system distribution lines for utility engineers, consultants, educators and manufacturers. It will review the fundamentals of this topic, examine the advantages and disadvantages of methods used, and present line configurations and schemes.

? IEEE P1605 â„-, “Guide for Comparison of Existing Installation Requirements for Electrical Distribution and Utilization Equipment in North America and Europe,” will be a new standard that compares installation practices for a variety of equipment, e.g., enclosed high-voltage and low voltage switchgear, transformers, motor control centers, switchboard and panel boards. Comparison will involve such North American standards as the National Electric Code in the U.S. and the Canadian Electric Code and relevant IEC and EN documents used in Europe.

? IEEE P1410 â„-, “Guide for Improving the Lightning Performance of Electric Power Overhead Distribution Lines,” which identifies factors contributing to lightning-caused faults on overhead distribution lines carrying voltages of 69 kV and below, will be revised.

The changes will suggest improvements to existing and new systems and present alternatives to reduce lightning-caused flashovers.

About the IEEE Standards Association

The IEEE Standards Association, 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 to ensure that products and services are fit for their purpose and perform as intended. The IEEE-SA has a portfolio of more than 870 completed standards and more than 400 standards in development. Over 15,000 IEEE members worldwide belong to IEEE-SA and voluntarily participate in standards activities. For further information on IEEE-SA see:
