초록
Traditionally, instrument transformer of the ferromagnetic core type have been used for measuring current in GIS(Gas Insulated Switchgear). Recently, with the introduction of digital technology at the protection relay or measurement device level, the use of new current sensor can be foreseen. Current measurement by means of Rogowski coil is just one illustration of this. This paper describes the progress of development of Rogowski-coil type CT for application in 170kV GIS.
