Experimental investigation of transient earth voltage and acoustic emission measurements of partial discharge signals in medium-voltage switchgears

Partial discharges (PDs) are small electrical sparks that can occur in insulation systems in high-voltage equipment, and if it is kept for a long time, electric equipment and power grid will become very dangerous. Switchgears are the key equipment in the distribution power network. In this paper, by using artificial defect models in the laboratory, partial… CONTINUE READING
