【Abstract】 The merits of Rogowski coil are good linearity, no magnetism saturation, very large scope of measurement frequency and simple structure and so on. It makes Rogowski coil suitable to measurement on-line, digital relay, control in time, diagnoses of fault and measurement of slim current by circuit disposing. The basic theory and the realization is given, and the three applications are given. At last, the test results with rated current is 0.2 A, prove the precision to be grade 0.2.更多还原
