Description

technical field [0001] The invention relates to an intelligent test device and a test method, in particular to an intelligent test device and a test method for a residual current operated protector. Background technique [0002] With the increase in the frequency and service life of household appliances and their power supply lines, leakage is prone to occur. Modern household power supply circuits are equipped with circuit breakers or similar protectors with different levels of residual current protection functions. Such circuit breakers or protectors The inspection of residual current operating characteristics is a very important test, and it is also an important standard for checking whether the circuit breaker or protector can be used normally. At present, the following three types of defects generally exist in the test equipment and test methods of residual current operated protectors: (1) The wiring is complicated, the test operation steps are complicated, and the test ...
