Abstract
For measuring the transient electromagnetic fields and related quantities created by disconnector operations in GIS, one needs the wide bandwidth sensors with simple transfer functions. This paper describes a new developed electric field sensor to measure the very fast transient electric fields and voltages, and the measuring principle, design and construction of planar electric field sensor are described. A calibration and/or correction technique of the sensor is investigated which enables an accurate determination of the sensor response to the time-changing electric fields. As a consequence, the low voltage calibrations certify that a rise time of 1.7 [ns] is achieved for the planar electric field sensor and a total bandwidth extending from several Hz to 200 MHz for the measuring system which presents the constant division ratio as a function of frequency.
