THE DIAGNOSTIC TESTING OF HIGH VOLTAGE SILICON …

silicon carbide surge arrester in service for over 13 years exhibit some form of degradation. Not only do these degraded arresters present a threat to system reliability, but the tendency of silicon carbide arresters to fail explosively also presents a hazard to both adjacent equipment and personnel.

Silicon Carbide Lightning Arresters Working Principle

Silicon Carbide Arresters (SIC): The Non linear lightning arrester basically consists of set of spark gaps in series with the silicon carbide non linear resistor elements. Lightning arresters are connected between the phase conductors and ground. During normal system operating voltage conditions, the spark gaps are non conducting and isolate the high tension (HT) conductors from the ground.

Lightning arrester - Wikipedia

2019-5-7 · The result is that electrons go through the lightning arresters rather than traveling on to the television set and destroying it. A lightning arrester may be a spark gap or may have a block of a semiconducting material such as silicon carbide or zinc oxide. "Thyrite" was once a trade name for the silicon carbide used in arresters.
