Under normal running condition, the insulation monitor can monitor the voltage of the two section bus, and calculate the insulation resistance of the bus to the ground by monitoring the bus voltage. When the bus is on the insulation resistance is lower than the set alarm limit when the door insulation monitor into branch patrol, measured insulation down branch and insulation resistance value, at the same time the alarm information through the serial bus upload to the master machine. The utility model has the advantages of reliable performance, perfect function, and friendly man-machine interface, and can be widely used in power plants, power plants and substations in the electric power, petroleum, chemical, railway and coal industries. The 1.2 main functions The main functions of THJY001 implementation are: 1, the system adopts DCS control mode, which is easy for users to expand. At most 8 external insulation monitoring modules can be extended to monitor the insulation status of the 256 branches; 2, the button set whethe
