    China High Quality insulation resistance testing of cables Suppliers – Dielectric Loss Tester for Live Capacitive Equipment GDDJ-HVC – HV Hipot

    General Information There are usually two ways to monitor the insulation condition of high voltage electrical equipment in substations: online monitoring and live (portable) online detection. The former one can obtain the characteristic parameters reflecting the abnormal insulation of the equipment at any time, which is convenient for automatic management. However, the investment is relatively large, the installation and construction are relatively troublesome, and regular maintenance is needed. For the latter, it has the advantages of low investment, highly targeted, easy to install, maintain and update. If the sampling unit is installed in the electrical equipment in advance, a regular detection can be done for electrical equipment in operation, and insulation flaw can be found in ...

  • OEM Best megger pf tester capacitance Factories –  Online Monitoring System of Circulating Current on Cable Sheath GDCO-301 – HV Hipot

    OEM Best megger pf tester capacitance 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...
