The present invention proposes a protection relay system using a complex sensor to execute the protection relay of a rapid and accurate power facility by prescribing the initial phenomenon of insulation deterioration and destruction in the power facility as arc and spark, by sensing the generation of the arc and the spark through an illumination sensor and a sound sensor, by executing an accumulated calculation or a moment comparing process, by accurately obtaining the deterioration start point of each components in the power facility. An insulation deterioration diagnosis and protection relay control method for the power facility of the present invention comprises the steps of inspecting and detecting the illumination of sound and flash according to the generation of the arc by monitoring the generation of the arc in the corresponding part through the sound sensor and the illumination sensor installed in a connecting unit and monitoring target electric equipment; of determining the semanticity of detection data by comparing the illumination, the frequency, and the sound size with a reference value within a DB by extracting the illumination, the frequency, and the sound size from the detected sound and the detected flash; and of generating an inspection trip signal when the inspection sound value and the inspection illumination value detected in the semanticity determination of the inspection and detection data is the data value including the semanticity, and the inspection detection value is over respective setup reference values and of generating fire warning and the restriction of load power supply by operating a block relay and an alarm unit by generating a spot trip signal when the inspection detection value is under the respective setup reference values. |
