<p>PROBLEM TO BE SOLVED: To provide a GIS capable of easily detecting the voltage in a GIS container. SOLUTION: In a shield 2 of a wire wound current transformer arranged in a GIS container, a notch opposed to a conductor 4 is provided, here, an electrode 5 opposed to the conductor is provided. Since a stray capacitance 7 appears between the electrode and the conductor, a divider capacitor 8 is connected between the electrode and the earth, voltage between both ends of the divider capacitor is detected by a means 9, so as to measure the voltage of the conductor. Further, this electrode is formed in a separate unit from the shield, the electrode can be mounted outside the shield. This voltage detection part 50 can be provided in a conventionally existing current transformer.</p> |
