Infrastructure Construction for Meter Test and Performance Analysis for Expired Meters based on Available Period

Recently, function and role of electricity meter is changing significantly along with IT technology development. In North America and Europe area, especially, and major electric power companies in the world, demand for mechanical electricity meter is decreasing while electronic electricity meter implementation is continually increasing. Korea Electric Power Corporation (KEPCO), a Korean electric power company, started full scale introducing electronic electricity meter from 2000. Most of the high voltage electricity meters have been changed with electronic type electricity meter. Mechanical electricity meters work as major part in low voltage currently, but these are expected to be changed with the electronic type electricity meter near future. In relation with this situation, future electricity meter operation and maintenance will be focused to electronic type. This study introduce infrastructure construction for the quality improvement of electricity meters, performance analysis for expired meters based on available period, and investigate possibility of extending its lifetime.
