Dielectric testing of gasinsulated HVDC systems
Development of DC transmission technologies is progressing rapidly and with this, gas-insulated HVDC systems are of particular interest. Since no standards for (dielectric) testing of HVDC gas-insulated systems are currently in place, CIGRE Joint Working Group JWG D1/B3.57 considered this topic in detail. Based on the basic phenomena and insulation properties at DC voltage and overvoltage stresses, a dielectric testing procedure is suggested. It comprises type testing including the DC insulation system test, routine testing and onsite testing, as well as the prototype installation test.
