ABSTRACT:
An electrical arrester structure includes an arc quenching chamber in which are located a pair of spaced principal electrodes between which a quenched arc gap is formed, an associated blow-out coil for magnetically influencing and expanding the arc formed between these electrodes and an auxiliary electrode which together with the principal electrode adjacent thereto forms an auxiliary arc gap. The auxiliary electrode is connected directly to one end of a leakage resistor and the other end of this leakage resistor is electrically connected either through the blow-out coil or directly to the principal electrode which is adjacent the auxiliary electrode with the result that the auxiliary arc gap will fire before the voltage protective level of the arrester is reached and cause the leakage resistor which is series connected with the quenched arc gap to be bridged.
