000000238 520__ $$aThe surge arresters diagnostics based on infrared temperature measurement was evaluated. The 110 kV metal oxide arresters with porcelain housings with two different varistor columns were used. The first one consisted of new varistor elements and the second one consisted of in field degraded varistors. The internal temperature was measured by means of two Tinytalk probes inserted in the varistor column at the bottom and at the top. The external temperature of the housing was measured by means of infrared camera. The maximum temperature of new varistors has grown about VC over the ambient temperature and the external temperature of the housing increased about 1°C only. The temperature of deteriorated varistors increased up to 15°C. Therefore, the arrester housing temperature increased about VC.
