| Abstract: | This paper analyzes the ability of 45 Hz and 55 Hz inter-frequency measurement to suppress the power frequency 50 Hz interference signal, studies the deviation of the current transformer error measured by the inter-frequency measurement method and the compensation method. The on-site measured data verifies the rationality of the method and the effectiveness of anti-interference. |
