ABSTRACT: This paper studies the method for measuring
the loop resistance of GIS conductor pole based on the super capacitor
producing impulse current up to several thousand amperes. This method overcomes
the limitations of conventional diagnostic method. Typical GIS conductor poles
are chosen. Based on FEA and lab tests, the effect of different forms of
current and contact condition, relationship between the temperature of contact
and the loop resistance is researched. In full- scale testing under realistic
operating conditions on the new 220 kV GIS using prototype instrumentation a very
good sensitivity in an early stage was obtained.
