ABSTRACT:
A device for detecting an electrical abnormality in an electrical device filled with insulating gas. A surface on a light reflecting prism placed within the electrical device carries a color indicator material. The color indicator material changes color when acidic gas is present. This gas is formed when an electrical abnormality such as a short circuit occurs in the presence of the insulator gas. A light source provides light to the prism which reflects light back having a color which varies according to the color of the color indicator material. The color of the reflected light is analyzed to determine if an electrical abnormality is present.
