In order to effectively ensure the electrical characteristics of electrical systems and subsystems of space camera and reduce the potential risks of power on, the method for static test of electrical interface before systems power on was proposed.Firstly, the electrical interface of space camera was defined and classified, and the com-mon test methods for electrical interface of space camera were proposed.Secondly, the effectiveness of the proposed test method for identifying the electrical characteristic of system and reducing the potential risks of power on were discussed.Finally, the resistance test model of digital multimeter was set up, the behaviors and notes using digital multimeter to test the different circuit networks’ resistance were analyzed.The experimental results show that, in a single point failure case, the static test for electrical interface of space camera before system and subsystem power on can effectively identify the electrical interface characteristic and reduce the risks of system power on.
