The Hilbert modulus is defined as the sum of the square of a signal and its conjugation.Hilbert modulus is used to covert the fundamental component in original phase current to direct current component,the fault characteristics frequency of bar break is transformed into the twice slip frequency.The problem is solved that fault characteristic component in the spectrum analysis of the current is easily to be blanketed by fundamental component and is hard to highlight fault characteristics.

将Hilbert模量定义为原始信号与其共轭信号的平方和，利用Hilbert模量将原相电流中的基波分量转变为直流分量，原频谱分析的转绕组断条的故障特征分量转变为频率为二倍转差频率的电流分量，决了相电流频谱分析方法中断条故障特征成分容易被基波湮没而难以突出故障特征的问题。
