The basic principle of SF6 infrared imaging leakage detection technology and the application cases in UHV substation were introduced. The SF6 gas was tested without interrupting power supply, and the leakage points were located precisely. The results show that the SF6 infrared imaging leakage detec-tion technology could test the equipment targetedly and improve the detection efficiency through combining the change of SF6 gas pressure showed in relay.
