abstract = "Based on the analysis of advantages and disadvantages of the DC system insulation monitoring principle, a new DC system insulation monitoring device is put forward, which is a combination of balanced bridge and switching resistance. Bus voltage detection circuit and branch drain current acquisition module are designed to monitor the insulating state of bus and branch, respectively. The STM32 microcontrollers are used as master MCU and acquisition MCU. In this way, a decentralized modular multi-core detection structure is established. Further, the hardware and software parts of the DC system insulation monitoring device are designed in detail. By testing the prototype in a variety of ground states, the accuracy of ground resistance measurement, branch positioning and fault alarm is verified.",
