China High Quality megger earth tester Manufacturers – 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... -
