| Abstract: | in order to make safety check and guick calibration the widely-used leakage current protector, the author develops a type of digital instrumentation which can measure the leakage action current of the leakage current protector and the breaking time of the switch under that electric current. Practice proves that the design of this instrument is reasonable since it can quickly measure the above-mentioed two indexes with sufficient precision. |
