Abstract
This paper describes the development of a new voltage recorder for the voltage management of power distribution lines. The voltage characteristics and measurement problems for the power distribution lines are analyzed and the functions required for the recorder are discussed. Applying a dual-slope A/D converter with low noise characteristics the voltage measurement algorithm, design and implementation for the recorder are discussed. Finally, the voltage variations of long-duration over-voltages or under-voltages, and short-duration temporary interruption based on IEEE 1159 are analyzed. It is verified with the experiment.
