【Abstract】 Considering the problem of traditional monitoring system no longer adapting to test the frequency -shift in non -insulation frequency - shift auto -block system, according to the conversion principle from time domain to frequency domain, frequency spectrum analysis method was applied to quantitatively analyze the frequency- shift. A simulative testing frequency - shift system was designed in this paper. Executions show the measurement accuracy is in good agreement with the requirement of the non -insulation frequency - shift auto -block system monitoring frequency -shift.更多还原
