BUSCADOR RECOLECTA

Corona discharge and total discharge from the tip of a copper wire. The ground plane is placed at 15 cm from the tip. The voltage needed to break the air insulation is around 87 kV.

Corona glow in a high-voltage cable at 17 kV and in a typical connector tip at the end of the cable. This picture was taken to test if the connector would affect in the measurements of partial discharges in radio-frequency with antennas.

Surface discharges and electric-arc on a polyethylene layer. The cylindric electrode is connected to a high-voltage source. As the voltage is raised, partial discharges appear at the base of the electrode giving a faint purple glow. A further increase in the voltage creates short arcs that do not reach the ground metallic plane. Finally, for voltages above 14 kV, the arcs are able to shortcircuit the electrode to ground.

Faint corona glow around a high voltage cable at 17 kV. The electrodes below the cable are made of stainless steel and connected to ground. The electrode on the cable is only a weight to press it to ground. The glow at the left of the picture is due to a wire wrapped around the cable and also connected to ground. Photograph taken in the High-Voltage Laboratory at University Carlos III of Madrid.
