| Abstract: | The principle of Rogowski coil and two working states are presented. The measurement apparatus aiming at high frequency large current is designed. Furthermore, the experimental result of frequency characteristic and linear degree about the measurement apparatus of high frequency heavy current which of center frequency is 50Hz and rated current is 600A are given. Test results and practical experiments prove that the linearity of the measuring apparatus is less than 0.5% when working frequency is between 10-100KHz. |
