Leakage of SF6 gas in a lot of electrical equipments is inevitable.Aiming at problems of negative corona discharge and electrochemical gas leakage detection technologies such as bad real-time and low precision of measurement
a new type of photonic crystal fiber SF6 gas sensor is designed and use harmonic detection method and computer wireless transmission network to construct remote real-time monitoring system.Experiments show that relative error of gas detecting is within 2 %
