Quick guide




Ofil’s DayCor®  Superb pinpoints corona PD on cables inside breaker cabinets

Partial discharge (PD) produces UV radiation, corrosive materials and audio noise. PD on conductors develops at sharp angles, broken strands, bird cages, contamination and if the conductor dimension does not fit its load. Ofil’s DayCor® Superb draws immediate attention to PD sources, designating the exact location of the emitting source. Notice how the user of the camera changes the camera gain which helps pinpointing the radiation sources
