摘要

[PROBLEMS] To provide a magnetic flux measuring apparatus of a stationary induction electric device and a magnetic flux measuring method thereof wherein the magnetic flux can be precisely measured without being affected by a DC offset component superimposed in a measuring system and wherein the magnetic flux can be constantly measured without limiting the magnetic flux measuring time interval. [MEANS FOR SOLVING PROBLEMS] In a magnetic flux measuring method, which uses the voltage waveform of a stationary induction electric device (2) to measure the magnetic flux of the stationary induction electric device (2), the voltage waveform (121) of the stationary induction electric device (2) is inputted to a negative feedback amplifying means (14), in which a feedback circuit is configured by use of a lowpass filter, and the outputs of the negative feedback amplifying means (14) are integrated by a integrating means (15), thereby determining the magnetic flux (151) of the stationary induction electric device (2).
