Picosecond high-voltage pulse measurements
Review of Scientific Instruments, 2021This paper presents capacitive sensors based on oxide dielectric substrates that provide a high attenuation factor of up to 30 · 103 with a transient time of ∼38 ps. The sensors made it possible to significantly reduce the number of attenuators and increase the bandwidth of the measuring path.

Fault Location Using Voltage Measurements
IEEE Power Engineering Review, 2001This paper presents a novel method for locating short-circuit faults in electric power systems. The origins of the method are in the concept of vulnerability contours, which is used in assessing the likelihood of voltage sags effecting a given network area. The method is applied in an off-line step and an on-line step.

Laboratory measurement of impulse voltages
Electrical Engineering, 1933A brief description is given of impulse generators and the discharge circuit constants involved in obtaining impulse voltages of the desired wave shapes. The relative influences of these constants are recognized and simplified discharge circuits are given. The variations in the wave shape and the reasons for the differences in sparkover values obtained

Ultrafast pulses can be measured by a resistive divider or a capacitive divider (Sect. 17.1). In terms of the ease of construction and characterization, the resistive divider is a better choice. The divider is typically consisted of a high value resistor and a 50 Ω resistor, designed to match the impedance of a standard coaxial cable. The configuration
