The present invention relates to a current measuring device and a gas insulated switchgear including the same, capable of allowing a device to be compact and lightweight and increasing an output voltage of the device by using a Rogowski coil. For the purpose, the current measuring device comprises: a Rogowski coil stacked in multiple stages to increase the output voltage; and a ring-shaped Rogowski coil current transformer wherein the Rogowski coil is insert-fixed, and an output terminal is installed on one side. In addition, the gas insulated switchgear includes the current measuring device, and includes an enclosure accommodating a plurality of the current measuring devices and a main circuit disposed at a center of the current measuring device. 본 발명은 로고스키 코일을 사용하여 장치를 소형화 및 경량화시킴과 아울러 장치의 출력전압을 증대시킬 수 있도록 된 전류측정장치 및 이를 포함하는 가스절연개폐장치에 관한 것이다. 이를 위해 전류측정장치는 복수개의 단으로 적층되어 출력전압을 높이는 로고스키 코일, 및 상기 로고스키 코일이 삽입 고정되고, 일측에 출력단자가 설치된 링 형태의 로고스키 코일 변류기를 포함한다. 또한, 가스절연개폐장치는 전류측정장치를 포함하고, 상기 전류측정장치를 복수개 수용하는 외함, 및 상기 전류측정장치의 중심에 배치되는 주회로를 포함한다.
