UHV: New Technology Promises to Help Deliver Future Energy Demands

    GENEVA, Switzerland, Aug. 3 /CNW/ - The leading experts in the field of
Ultra High Voltage or UHV are to begin defining the technical and safety
specifications for this promising new technology that is set to help deliver
the world's increased electrical energy demands. Ultra High Voltage could
offer a solution to the need for more electricity in a space-restricted world.
Countries active in this technology include Brazil, Canada, China, Japan,
Russia and the USA.
    The IEC (International Electrotechnical Commission) and CIGRE are to join
forces to develop international standards for Ultra High Voltage to ensure the
safe and efficient use of this technology, in areas likely to include
reliability and maintenance, as well as defining the tests for the measurement
of electromagnetic radiation from the power lines.
    IEC and CIGRE agreed on the joint work at the recent international
conference on UHV held in Beijing, China on 18-21 July 2007 attended by the
world's leading experts on the technology.
    One of today's challenges is being able to supply growing demand for
large amounts of electrical energy efficiently and with a minimal impact on
the environment. Often electricity is generated thousands of kilometres away
from the urban populations to whom it needs to be delivered and, in the
process of transmission, it loses energy.
    Ultra high voltage (UHV), defined as AC voltages of 1,000 kilovolts or
higher, or DC voltages of 800 kilovolts, or higher, is a highly efficient
means of transmitting large quantities of power over a transmission line. This
is because the higher the voltage on the line, the lower the current and
therefore the lower the loss.

    About IEC

    IEC is a not-for-profit, non-governmental organization that develops
international standards for all electrical, electronic and related
technologies. Founded in 1906 at the beginning of electrification, IEC produce
standards for a wide range of technologies and applications, including
electricity generation, transmission and distribution.

    About CIGRE

    Founded in 1921, CIGRE (International Council on Large Electric Systems)
is one of the leading worldwide Organizations on Electric Power Systems,
covering their technical, economic, environmental, organisational and
regulatory aspects.
