Electrolytic Lightning means is necessary to protectelectrical apparatus from lightning andhigh voltage static disturbances andsurges so as to relieve the abnormalvoltage and divert it from passingthrough the armature coils of an elec-trical machine or other electrical ap-paratus to ground, putting the apparatusout of service, meaning in many casesinterference with continuity of serviceand expensive FIG. 3.

It automatically offers avery high resistance to currents at nor-mal voltage so that normally the cir-cuits are not disturbed; it offers a verylow resistance to voltages above acertain critical value, in other words,only a small increase in voltage is re-quired for the arrester to work and re-lieve the abnormal conditions due tolightning. With this arrester thevoltage cannot rise to such a high valuethat the electrical apparatus will bedamaged; it offers a low effective re-sistance to currents o
