PISCATAWAY, N.J., USA, 13 February 2007 IEEE begins work on two
first-of-a-kind electrical standards: one for the measurement of power loss in
apparatus at low power factors and the other for handling sulfur hexafluoride.
It has also revised standards for shunt reactors and insulating oil and begun
to revise standards for dry-type transformers and the measurement of electric
power quantities.
The IEEE has begun work on IEEE P1715(TM), "Electrical
Power Apparatus Low Power Factor Power Measurements", which will be the first
independent standard to address the measurement of high-voltage power loss in
electrical power apparatus at the low-power factor conditions are found in power
transformers, high-voltage inductive-capacitive reactors, power cables and bushings.
The standard will identify measurement and on-site test methods and instrumentation
and recommend how to maintain the accuracy of the power-loss measuring systems.
In addition, the IEEE has begun to develop IEEE P1712(TM), "Guide for
Sulphur Hexafluoride (SF6) Gas Handling for High Voltage Equipment", which
will be the first independent guide for U.S. users on handling SF6 gas used in
electric power equipment. It will address state-of-the-art technologies and procedures
to minimize SF6 gas emissions from electric power equipment to protect the environment
during activities such as commissioning, decommissioning, refilling, sampling,
gas recovery, reclamation and recycling. It also will consider measuring devices
and personnel protective equipment.
The IEEE has also revised two standards.
The first is IEEE C37.109(TM), "Guide for the Protection of Shunt Reactors".
The revised version was made more comprehensive by the addition of reactor configurations
and reactor protection schemes.
The other revised standard, IEEE C57.106(TM),
"Guide for Acceptance and Maintenance of Insulating Oil in Equipment",
applies to mineral oil used in transformers, load tap changers, voltage regulators,
reactors and circuit breakers. It discusses such topics as analytical tests and
their significance for evaluating new and used mineral insulating oil, as well
as handling, storage, health and environmental procedures.
The IEEE has
also begun to revise two standards. On of these is IEEE PC57.12.91(TM), "Standard
Test Code for Dry-Type Distribution and Power Transformers". This work with
bring IEEE PC57.12.91, which provides a basis for the performance, safety and
the testing of these transformers, in line with current practice.
The other
revision project is for IEEE P1459(TM), "Standard Definitions for the Measurement
of Electric Power Quantities under Sinusoidal, Non-Sinusoidal, Balanced, or Unbalanced
Conditions", which offers definitions to quantify the flow of electrical
energy in single-phase and three-phase circuits. It also provides criteria for
designing and using metering instrumentation.
The IEEE has reaffirmed
four power-related standards:
· IEEE 1255(TM), "IEEE Guide
for Evaluation of Torque Pulsations During Starting of Synchronous Motors";
· IEEE C37.96(TM), "IEEE Guide for AC Motor Protection";
· IEEE C57.12.59(TM), ";IEEE Guide for Dry-Type Transformer Through-Fault
Current Duration"; and · IEEE C57.94(TM), "IEEE Recommended
Practice for Installation, Application, Operation, and Maintenance of Dry-Type
General Purpose Distribution and Power Transformers".
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 based on current scientific consensus. The IEEE-SA
has a portfolio of more than 870 completed standards and more than 400 standards
in development. For 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 about the
