China High Quality Pd Test Of Cable Suppliers – Partial Discharge Online Monitoring System of Generators – HV Hipot
General Information Generally, partial discharge occurs at a position where the properties of the dielectric material are not uniform. At these locations, the local electric field strength is enhanced, and local electric field strength is too large, resulting in local breakdown. This partial breakdown is not the total breakdown of the insulating structure. Partial discharges typically require a certain amount of gas space to develop, such as gas voids inside the insulation, adjacent conductors, or insulating interfaces. When the local field strength exceeds the dielectric strength of the insulating material, a partial discharge occurs, causing many partial discharge pulses to occur during one cycle of applying the voltage. The amount of discharge delivered is closely related to the n... -
