The possibility of the classical response rate engineering and the long-term deconditioning of the gas-filled surge arresters is considered in this paper. The obtained results are compared with the same results obtained with the gas-filled surge arrester with application of an alpha radioactive source. The work is of an experimental nature. Experiments were performed on the multipurpose gas-filled surge arrester model under well-controlled conditions. The measurement uncertainty of the experimental procedure was less than 8 %. The results were processed by statistical data processing software. To draw impulse characteristics, the law of constancy of surfaces below the impulse voltage in the volt-second area, was used.
