Abstract
Digital simulations have been conducted to analyze the thyristor valve turn-on phenomenon while a valve arrester is conducting, which gives the most severe turn-on stress for the valve. The effects of various other parameters have also been clarified. Based on this analysis, two test methods are proposed that verify a valve turn-on during arrester conduction, and their effectiveness is described. The nonrepetitive turn-on test given in the IEC Std Pb. 700 and IEEE Std 857 is studied, and a new test voltage level based on these analyses is proposed
