Measuring low-current discharges from grounded rods under high background electric fields

This work presents the development of an inductive current sensor for measuring pulsating corona discharges observed under high background electric field. Laboratory and field experiments in different setups are used to corroborate the discharge features. The first location is on the roof of a regul...
