OEM Best test meger Factories – Online Monitoring System of Circulating Current on Cable Sheath GDCO-301 – HV Hipot
General Information Cables above 35kV are mainly single-core cables with metal sheath. Since the metal sheath of the single-core cable is hinged with the magnetic field line generated by the AC current in the core wire, the two ends of the single-core cable have a high induced voltage. Therefore, appropriate grounding measures should be taken to keep the induced voltage within the safe voltage range (usually no more than 50V, but no more than 100V with safety measures). Usually, the metal sheath of short line single-core cable is grounded directly at one end and grounded through gap or protection resistor at the other end. The metal sheath of long line single – core cable is grounded by three – phase segmental cross – connection. No matter which kind of grounding me... -

OEM Best power and distribution transformer 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...
