SIM Training and Development on Electrical Metrology
Introduction
About half of all manufactured products in the world is accounted for by individual items such as aircraft, motor vehicles and computers, together with their component parts. The other half mostly comprises goods manufactured in bulk. Of this, about half is in the automobile industry, other important sectors being aerospace and instrumentation. For most of these products their performance and perceived quality, and hence their commercial success, is determined by how well they are made. Electrical technology is increasingly being used in manufactured products. The performance of such products is therefore often evaluated by measuring to what extent the electrical quantities depart from specifications. The field of electrical metrology is also important in the performance evaluation of the electrical power transmission and distribution network of each country. Several electrical quantities need to be measured traceably to generate and distribute electrical power safely, economically and attending quality requirements. International telecommunication systems work reliably and efficiently, but for high rates of data transmission time scales across the world must be closely coordinated and must not fluctuate from microsecond to microsecond, from minute to minute or from day to day. In addition, traceable radio-frequency measurements need to be done to ensure the security and quality of the communication network.
This is what we call electrical metrology. All these measurements need to be reliable and traceable to a National Metrology Institute (NMI) in each country. This traceability is ensured by periodic calibration of the industry standards in the National Calibration Network of each country. Also, the calibration network standards are sent to the NMI to be calibrated periodically. In order to provide confidence among the traceability chains of each country, international comparisons on electrical quantities are held periodically among the several NMIs of the respective Regional Metrology Organization (RMO). Several RMOs have been setup in many parts of the world. The Inter-American Metrology System (SIM) is the RMO of the Americas.
Inter-American Metrology System (SIM)
The Inter-American Metrology System (SIM) resulted from a broad agreement among national metrology organizations from all 34 member nations of the Organization of American States (OAS). Created to promote international, particularly Inter-American, and regional cooperation in metrology, SIM is committed to the implementation of a Global Measurement System within the Americas, in which all users can have confidence.
The objectives of SIM are: (a) cooperate in the development of National Metrology Institutes in each country in the region; (b) contribute to the development of measurement infrastructure required to promote equity in trade; (c) foster competitiveness and quality of the manufacturing sector in order to promote trade and commerce; (d) identify sectors and institutions that can conduct specific multinational activities in support of metrology; (e) contribute to the development of metrological infrastructure required to protect the environment and to promote the general well-being of the population, including its health and safety.
For this purpose, measures taken by the members will help to achieve the following: (a) the establishment of national and regional measurement systems; (b) the establishment of a hierarchy of the national standards of each country and their linkage with regional and international standards; (c) the compatibility of results obtained from measurement processes performed in laboratories within the system; (d) the development of competitive technical and scientific personnel; (e) the collection and distribution of technical and scientific information and documentation; (f) the linkage with the several international organizations specialized in the area of metrology.
SIM has specific working groups each dealing with specific measurement quantities. For more details consult http://www.sim-metrologia.org.br
SIM Electricity and Magnetism Metrology Working Group
The SIM Electricity and Magnetism Working Group (SIM EM MWG) is concerned with (a) promoting closer collaboration among SIM laboratories in projects related to electrical metrology and measurement services, (b) optimizing the use of EM resources and services of the SIM laboratories and foster the development of these EM services so they may satisfy regional demands, (c) documenting the traceability of EM measurement systems in SIM laboratories and encourage the regional acceptance of this traceability, in accordance with international definitions and trends, (d) evaluating the current status of the ongoing international comparisons on electrical quantities among the SIM laboratories and studying the future EM comparison needs of SIM laboratories, (e) supervising SIM EM comparisons, taking the necessary measures to expedite them in case of delays, (f) harmonizing procedures proposed by the SIM EM MWG to perform EM comparisons of SIM laboratories and (g) evaluating the training and development needs of SIM laboratories.
In order to accomplish the above goals annual meetings have been organized attached to training and development events.
SIM Training and Development on Electrical Metrology
The main objective of the SIM T&D on Electrical Metrology is the training and capacity building of country representatives in the field of electrical metrology. For that it has been envisaged the organization of tutorials on electrical metrology, and the participation at the VIII International Seminar on Electrical Metrology (VIII SEMETRO) to be held in June 2009 in the city of Joao Pessoa/Paraiba, in Brazil.
The tutorial concentration will be on measurements related to the following dc/low frequency electrical quantities:
a) DC voltage,
b) AC-DC voltage and current transfer,
c) DC resistance,
d) Power and energy.
It is expected that the tutorials will promote the strengthening of electrical metrology activities within the region, increasing the recognition and reliability of metrological services that support international trade. For that the methodology proposed consists of, besides the exchange of experience among participants, the multiplication of such experience in their countries, through national meetings, seminars and other internal activities.
Audience
Scientists, engineers, managers, auditors, consultants and representatives from universities, governmental agencies, industry and commerce, calibration and test laboratories, and national metrology institutes.
