Abstract :
Such devices would be useful for monitoring line voltages in, for example, SF/sub 6/ gas-insulated bus ducts. The theory of the devices is described and the results of tests on a laboratory prototype are presented. Furthermore, the design of a device monolithically integrating a capacitive divider and an integrated-optics Mach-Zehnder interferometer is proposed.<>
