Abstract
This paper deals with the analysis results of surge voltage and current measured on information devices installed in a power substation. The power recorder to measure surge voltage and current was connected to signal lines near power transformers and switches, and the time resolution of the power recorder is 4 MS/s. Peak value of the measured surge voltage and current were ranges of 500~1,300v and 500~3,100k, respectively. During the period of measurement, over 5~10 events per day were recorded. Consequently, information devices installed in around high voltage power facilities should be designed considering the surge voltage and current caused in the condition.
