Study on Application of Distributed Fiber Optic Temperature Measurement System on Power Transmission Safety Testing

Cable is in the daily production, life everywhere. In power plants, factories, laboratories usually concentrated a large number of cables for easy wiring, maintenance, and beautiful. As people grow dependent on electricity, large concentrations of cable make the probability of fire accidents also increased. Current thermal effects will cause a current passes through the core of the heating cable and temperature continues to rise, rather than the normal duration of overheating or long-term work overload will make the cable insulation aging faster. When the condition reaches breakdown insulating protective layer, it will cause a fire, resulting in people's lives and property safety hazard. This paper studies the application of temperature on the light transmission of electrical safety and makes effort to improve the security level of automation power transmission, reduced power transmission risk.
