STANDARDS

PISCATAWAY,
N.J., USA, 21 October 2004 The IEEE has approved a standard
for overhead circuit reclosers and fault interrupters and revisions
to standards for electromagnetic interference in relays and for
relay circuit testing. It also began a project to revise a standard
for the conversion of power switchgear and approved new work to
proceed on a project for metal-enclosed, low-power switchgear.
The approved
standard, C37.60-2003™/Cor1, "Standard Requirements
for Overhead Pad-Mounted, Dry Vault, and Submersible Automatic
Circuit Reclosers and Fault Interrupters for Alternating Current
Systems Up to 38 kV--Corrigendum 1," corrects errors in the
original document.
One of revised
standards, C37.90.2™, "Standard for Withstand Capability
of Relay Systems to Radiated Electromagnetic Interference from
Transceivers," offers a common reference and test procedure
for evaluating the susceptibility of static protective and control
relays to single-frequency, radio frequency fields, such as those
from radio transceivers.
The other
revised standard, C37.103™, "Guide for Differential
and Polarizing Relay Circuit Testing," reviews and updates
this testing guide to account for the advent of new equipment
and procedures and changes at utilities.
A revision
project, IEEE PC37.59™, "Standard Requirements for Conversion
of Power Switchgear Equipment" provides guidance on switchgear
conversion for designers, manufacturers and contractors. A new
project, IEEE PC37.20.1a, "Amendment to C37.20.1--IEEE Standard
for Metal-Enclosed Low-Voltage Power Circuit Breaker Switchgear,"
will correct errors in with respect to dummy elements and metric
conversion.
The IEEE also
reaffirmed the continued use of IEEE 857™, "Recommended
Practice for Test Procedures for High-Voltage Direct-Current Thyristor
Valves."
The above
projects are sponsored by the IEEE Power Engineering Society.
About the
IEEE Standards Association
The IEEE Standards Association (IEEE-SA), a global standards-setting
body, develops consensus standards through an open process that
brings diverse parts of an industry together. It has a portfolio
of more than 870 completed standards and more than 400 in development.
IEEE-SA promotes the engineering process by creating, developing,
integrating, sharing and applying knowledge about electro- and
information technologies and sciences for the benefit of humanity
and the profession. For further information on IEEE-SA visit:

About the
IEEE
The IEEE has more than 360,000 members in approximately 175 countries.
Through its members, the organization is a leading authority on
areas ranging from aerospace, computers and telecommunications
to biomedicine, electric power and consumer electronics. The IEEE
produces nearly 30 percent of the world's literature in the electrical
and electronics engineering, computing and control technology
fields. This nonprofit organization also sponsors or cosponsors
more than 300 technical conferences each year. Additional information
