This paper reports on the work undertaken to determine the effect of the gas type on the high repetition rate performance of a triggered corona stabilised (TCS) closing switch at a charging voltage of 23 kV. The voltage/pressure (V/p) characteristics as well as the ability of the switch to operate at high repetition rates were measured with SF/sub 6/, air and six different SF/sub 6//air mixtures having an SF/sub 6/ concentration ranging from 75 to 2% by pressure. The high repetition rate tests were conducted with a high-power facility at a pulse repetition frequency (PRF) ranging from 500 Hz up to a maximum of 3 kHz. During the investigation, it was found that for the given nonuniform switch geometry the high repetition rate performance of the device was closely associated with the efficiency of corona stabilisation, as measured from the V/p characteristics. This was clearly manifested by the superior performance of most of the SF/sub 6//air mixtures tested, which displayed a more efficient corona stabilisation compared to pure SF/sub 6/. In contrast, air displayed the worst performance of all the gases tested, due to the weak V/p characteristic and inefficient corona stabilisation.
