The present invention refers to a differential protection process by Lipschitz exponent blocking, which is calculated from the Wavelet Transform Modulus Maxima (WTMM), which is used for differentiating and quantifying the abrupt changes in the edges or discontinuities that a current signal has, due to that it is possible to identify and distinguish a power electric current from an overexciting electric current from a short circuit fault electric current. This process has a wide range of applications in the schemes for protecting electric power transformers, avoiding any type of unanticipated faults, providing more safety.
