Abstract

This paper presents a new practical optical fiber voltage transformer (OVT). It is different from the existing OVT. It has the high voltage directly applied across the electro- optical crystal of the OVT sensor and the other OVT uses capacitors to divide the high voltage. New types of silicon rubber insulators in which full SF6 gas is employed for HV insulation. It offers so many advantages like small volume, light weight, high accuracy, immunity form electromagnetic interference, no loss, wide bandwidth etc. The transformer could achieve +/- 0.2 percent accuracy. Compared with the conventional 110KV voltage transformer, its weight is only 1/3 of the former, and its cost is less than 1/2 of the conventional SF6 voltage transformer.
