Abstract Aiming at the shortcoming that the measurement data of voltage transient signals is large and the calculation time of the traditional transient signal envelope extraction algorithm is very long and is not conducive to the practical application, a envelope extraction algorithm based on Hilbert transform and low-pass filter is proposed and used to the actual voltage transient signal.The result shows that the envelope extraction algorithm can ensure the result of the voltage transient signal envelope accuracy, shorten about 60% of the computing time than that of the traditional transient signal envelope extraction algorithm.
