  • Research on Steady‐State Thermal Behavior of SF6/N2 and CF3I

    Gas‐insulated lines (GIL) are widely used due to their many advantages in power plants and substations. The security and reliability of GIL is achieved by continues testing and monitoring. The main fault in the GIL compartments is overheating, which is rarely to occur, nonetheless, it cannot be ignored.

  • SF6/N2 Mixtures for HV Equipment and Practical Problems

    Abstract. Since SF 6 gas has a high dielectric performance and interrupting capability, it is used widely in the Electric Power Industry. Recently, it is recognized that SF 6 gas is a greenhouse gas and therefore, SF 6 /N 2 gas mixtures are proposed as a replacement of pure SF 6.
