Induced current estimation algorithm of gas insulated line

This paper presents the analysis of induced voltage and induced current in enclosure pipe of three-phase gas-insulated transmission line. The induced current and induced voltage are carried out so that generalized mathematical model can be obtained. The current is derived based on electromagnetics theory. The estimated results are compared with the measured results. The highest error from the comparison between the computed and actual data is 12.89% because a large amount of induced current cannot be measured accurately.
