  • Balanced dual-gap protector
    Patent number: 4558390
    Abstract: Disclosed is a dual-gap protector wherein both gaps will break down essentially simultaneously when a pulse of either polarity having a sufficient magnitude appears. An annular electrode is provided in the housing so as to form parallel gaps with respective end electrodes. The electrodes include a surface coating of a photoemissive and/or thermionic material so that light emission or heat resulting from the breakdown of one gap will influence the breakdown of the other gap.
