Abstract
The measurement of transient phenomena in gasinsulated switchgear (GIS) has become a problem of interest to both utilities and manufacturers. Such transients have been responsible for a significant number of in-service faults and will probably be the critical parameter for dimensioning of GIS for system voltages over 550 kV. This paper describes the design, construction, and use of planar capacitive dividers and measuring systems which achieve subnanosecond rise times, response to below 1 mHz, and constant division ratio as a function of frequency.
