The invention relates to a method for avoiding and indicating fraudulence, in particular to an electricity steal-resistance load management method. The method acquires each subharmonic signal for detecting current circuit in real time, selects the harmonic signal with minimum amplitude in a special frequency range, and takes the frequency of the harmonic signal with minimum amplitude as the frequency of a detection signal; therefore, the selected detection signal initiatively avoids the harmonic signal with larger interference. The invention overcomes the effect that only disturbing signals with fixed frequency can be sent in the prior art and guarantees the accuracy of detecting results. Meanwhile, the method can detect various electricity-stealing incidents such as the current circuit is open circuited, the current circuit is short circuited, and a high-ratio current transformator is replaced, thereby being an electricity steal-resistance load management method for detecting various electricity stealing over all.
