<p>PROBLEM TO BE SOLVED: To detect the polluted state of spark gaps using the wave forms measured at different points through spark gaps and a gap for testing so set as to have higher dielectric strength than that of each spark gap. SOLUTION: Wave forms is measured at two or more different positions having at least one spark gap GS between them in, for example, a circuit comprising spark gaps GS and based on the two or more measured different wave forms, the polluted state of spark gaps existing between these two or more different positions can properly be detected, so that the labor necessary for maintenance of the spark gaps can be lessened.</p> |
