The insulation monitor is designed to ensure the reliable operation of the power dc system and the protection equipment. Its basic function is to monitor the bus voltage and the ground insulation resistance of the dc system online, and show the voltage value of the bus and the resistance value of the positive and negative bus. When the busbar is too low in insulation resistance, alarm signal is issued, and the alarm threshold parameter can be set manually. Online monitoring device has a branch inspection functions, you can check each branch of the insulation resistance, through the RS485 serial port, detection device dc system can be positive and negative bus bar of the insulation resistance of beam to system monitoring unit.
