Study on Intelligent Multi-circuit Automatic Test System for Insulation and Resisting Voltage

For overcoming the error brought by testers and testing methods in course of testing insulation and resisting voltage, the design method is put forward, which is used for the intelligent multi-circuit automatic test system for insulation and resisting voltage, The working principle, the composition of hardware and the realization of software are introduced. The system is established with supervision PC and slave computers. In supervision PC, software of data management and analysis is designed with VB6.0, the slave computer imposes the testing stress and collects data with the single-circuit instrument for insulation and resisting voltage, and chooses test channels with PLC by optimizing control algorithm. Long-term field operation shows that the system features simple operation, good man-machine conversation, stable performance, accurate measuring result and fast fault diagnosis.
