摘要：
A lightning arrester monitor which comprises an oxygen gas sensor (10) provided in a lightning arrester having a zinc-oxide-type element made of zinc oxide, the main component thereof, and other oxides added thereto; the oxygen gas sensor (10) measures the oxygen concentration of the element which increases as degradation thereof goes on. The monitor makes it possible to assess degradation of the zinc-oxide-type element with ease, without requiring any complicated electrical circuit for detecting leakage current.
