Research and Application of a New Electric Coupling Device

With the increase in the size of the distribution network, as the overhead cable that accounts for the largest proportion in the urban power grid, the importance of electricity inspection and phase detection is also increasing. In order to avoid the shortcomings of traditional electroscope and the possible serious consequences caused by incorrect phase-detecting, this paper proposes a new type of electric coupling device, introduces the structure and performance of the device, and analyzes its advantages and practical applications. This electric coupling device can measure, calculate, analyze and report the real-time status of transmission line operation, and it can fully meet the requirements of engineering that is economical and practical, safe and reliable, and intuitive judgment.
