Nanosecond resistive high-voltage probes for transient ground rise measurement in gas-insulated switchgear. Part I: Newi probes with wire-wound resistors

This paper describes a 5-ns rise-time resistive voltage probe for use up to 150 kV. It is based on a wire-counterwound design and uses low-voltage arms incorporating fast switching diodes for oscilloscope protection. Much attention was paid to reducing inductance in the system through a compact layout, while still ensuring adequate dielectric insulation.
