Phenix technologies offers both economical and easy to use partial discharge and radio influence voltage measurement systems which may be purchased separately to be used with. Electric discharge occurs due to the ionized air which results in corona. Partial discharge (pd) is the most unwanted phenomenon in high voltage insulation system. A corona discharge creates unipolar ions that can diffuse to particles in the airstream and an electrometer measures the amount of charge that is transferred from the ions to the particles. Partial discharges partial discharges (pd) occur between layers of isolation that have different characteristics.
The dfa300 partial discharge detector can locate partial discharge (pd) in a few seconds. It represents a local region where the air (or other fluid) has undergone electrical breakdown and become conductive. The pds™ allows online partial discharge detection on underground cable accessories and equipment for safety and maintenance purposes. When the voltage applied with tuned narrow band detectors, the partial discharge measurements can be detected with a sensitivity less than one. Corona phenomenon is electrical discharge with low sound or light color glow when air insulation is partially destructed by applied voltage first, set gain of each device as a default value, and check if corona image is generated.
