The invention discloses an AC / DC
lightning arrester combined action tester which includes a
power frequency power supply, a back-to-back
analog device, a multiple waveform generator and an
impact current generator, wherein, ground terminals of the
power frequency power supply, the back-to-back
analog device, the multiple waveform generator and the
impact current generator are grounded in parallel; power supply ends of the
power frequency power supply, the back-to-back
analog device, the multiple waveform generator and the
impact current generator are switched and connected in parallel by a switch; a
voltage divider and a specimen parallelly connected with the
voltage divider, wherein, the
voltage divider and the specimen are parallelly connected among the parallel connection ends and the ground terminals of the power frequency power supply, the back-to-back analog device, the multiple waveform generator and the impact current generator which are switched by the switch; an oscillograph which collects output signals output by output ends of of the power frequency power supply, the back-to-back analog device, the multiple waveform generator, the impact current generator and the
voltage divider, and transmits the collected signals to a combined action measuring and controlling
system.
