For Release:
Immediate
PISCATAWAY,
N.J., 14 October 2002 The Institute of Electrical and Electronics
Engineers Standards Association (IEEE-SA) Standards Board has
approved two power generation standards: one for electronic devices
that compensate for voltage fluctuations and the other that revises
a standard for temporary grounding in substations. It also has
approved the start of work on a new standard to calculate short
circuit currents in power systems and the revision of standards
on transformer impulse tests and safety cabling in nuclear plants.
The new standard,
IEEE 1585 (TM), "Guide for the Functional Specification of
Medium Voltage (1-35kV) Electronic Series Devices for Compensation
of Voltage Fluctuations," provides information on user requirements,
installation and start up for medium-voltage, solid-state devices
that compensate for voltage fluctuation. These devices generally
contain such components as an inverter, rectifier or dc-to-dc
converter, energy storage device and injection transformer.
The revised
standard, IEEE 1246 (TM), "Guide for Temporary Protective
Grounding Systems used in Substations," expands the existing
standard by adding new definitions, examples of differences in
body current with various temporary grounding practices, and the
results of recent tests of temporary protective grounding equipment.
The three
projects begun involve one new standard project and two revisions
to existing standards:
· The
new standards project, IEEE P551 (TM), "Recommended Practice
for Calculating Short-Circuit Currents in Industrial and Commercial
Power Systems," will address the design of electric power
circuits so equipment is adequately rated and protected against
short circuits or fault currents. Equipment covered includes protective
device sensors like series trips and relays, passive equipment
that may carry short circuit current, and interrupters like circuit
breakers and fuses.
· The
revision to IEEE PC57.98 (TM), "Guide for Transformer Impulse
Tests," will update and expand this guide, which helps interpret
and apply the impulse testing requirements of the IEEE Standard
Text Codes for Transformers.
· The
revision to IEEE P690 (TM), "Standard for the Design and
Installation of Cable Systems for Class 1E Circuits in Nuclear
Power Generating Stations." will update requirements for
safety-related electrical cable systems and associated circuits
in nuclear power stations in areas such as fire protection, raceways,
separation, cable performance and acceptance testing.
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: http://standards.ieee.org/.
About the
IEEE
The IEEE has more than 375,000 members in approximately 150 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
