Paper Abstract

This paper describes a mixed fiber optical measuring system for the isolated phase busbar. As the magnetic field in the isolated phase busbar is only related to the busbar current, the current sensor, which makes up of the diamagnetic SF-6 glass with the thin-film polarizer and analyzer at both its ends, is placed inside the enclosed shell but outside the busbar, and the distance from the current sensor to the axis of the busbar depends upon the value of the current measured. The laboratorial experiment shows that the optical measuring system is reliable for using in the power system instead of the conventional current transformer.
