A remote insulation test device for high -voltage electrical motors is introduced. To meet system requirement, a new -generation electronic insulation tester incorporating RS -485 communication module and control module was independently developed. Based on Siemens S7-200 PLC the system can control high-voltage motor insulation monitoring devices, high voltage relays and mechanical grips. Communication between the touch screen, PLC and insulation tester was established, realizing remote insulation measurement for high voltage motors. The device improves the automation level of high-voltage motor insulation test, reduces the frequency of equipment maintenance and ensures personal safety.
