  • The development of the line... The development of the linear Rogowski coil for measuring large impulse current
    Liao Ruijin; Sun Caixin; Gu Leguan Proceedings of 1998 International Symposium on Electrical Insulating Materials. 1998 Asian International Conference on Dielectrics and Electrical Insulation. 30th Symposium on Electrical Insulating Ma, 1998
    Conference Proceeding

    This paper describes the theory, design of the linear Rogowski coil, and analyzes its properties. The testing results show that it can measure not only large impulse (or power-frequency) current but ...

  • The harmonic analysis metho... The harmonic analysis method and its application in the on-line detection of electric equipment insulation
    Liao Ruijin; Wang Zhongyi; Sun Caixin ... Proceedings of the 6th International Conference on Properties and Applications of Dielectric Materials (Cat. No.00CH36347), 2000, Volume: 1
    Conference Proceeding

    This paper describes the harmonic analysis method which can be used to measure the resistance current of the metal oxide arrester (MOA) and the dielectric loss of the capacitive apparatus. The theory ...

  • On-line detection of gases ... On-line detection of gases dissolved in transformer oil and the faults diagnosis
    Liao Ruijin; Sun Caixin; Chen Weigen ... Proceedings of 1998 International Symposium on Electrical Insulating Materials. 1998 Asian International Conference on Dielectrics and Electrical Insulation. 30th Symposium on Electrical Insulating Ma, 1998
    Conference Proceeding

    This paper describes the theory of on-line detection of six kinds of gases-H/sub 2/,CO,CH/sub 4/,C/sub 2/H/sub 4/,C/sub 2/H/sub 2/,C/sub 2/H/sub 6/-which are dissolved in transformer oil, and ...
