Workshop
A 2-day Workshop investigating issues concerning powerline harmonics
generated by electrical and electronic products
Recent standards and legislation have called for limits on powerline
harmonic emissions from electrical and electronic equipment that could cause
increased product costs measured in billions of dollars! This workshop will
examine the bases used to determine the present limits and develop positions
for the US to take in future developments. For effective answers we must
have inputs from power utilities, manufactures and consumers. Thus we wish
to:
· Open a dialog on this subject between manufactures and electric supply
utilities in North America
· Develop a common understanding of the powerline mains environment and the
economic implications of various strategies for managing harmonic emissions
in public power distribution systems
· Develop US proposals for the International Electrotechnical Commission
(IEC) initiative revising the IEC harmonic emissions standard (Document IEC
61000-3-2) to cover electrical/electronic products connected to public
powerline mains distribution systems in North America
· Develop US proposals in the above IEC initiative to cover
electrical/electronic products connected to mains distribution systems in
the European Union and elsewhere throughout the world, which are as
consistent as possible with the US requirements
About half of the time will be devoted to prepared presentations with the
remainder to informal discussions among the participants.
