Abstract :
This paper presents a new type contact less voltage sensor which is based on the electromagnetic induction coupling principle. Induction lines that are laid under the aerial conductor are used for getting induction voltage signal, and then we could calculate the system voltage through voltage transformation matrix. The result of simulation shows that, contact less voltage sensor can catch voltage signal accurately, its working condition is stable.
