Abstract A HHT (Hilbert-Huang Transform)-based lightning shielding failure and back striking identification method on 1 000kV UHV transmission lines is proposed by considering antecedent development. Firstly, its equivalent model is established by ATP-EMTP based software. The effects of antecedent development on lightning over-voltage on transmission lines are investigated. Furthermore, the transient processes of over-voltages of shielding failure and back striking after lightning transmission lines are also analyzed. The lightning over-voltage signal on transmission line is decomposed by using empirical mode decomposition. Hilbert transformation is conducted on the first four intrinsic mode function which includes majority of high-frequency signal. The transformed instantaneous amplitude of IMF will be chosen as characteristic quantity. Meanwhile, its variance contribution rate will be calculated. In this case, the identification of lightning shielding failure and back striking on transmission lines is realized. The simulation and evaluation of measured data show that the method can effectively identify lightning shielding failure and back striking. It also avoids influence of ground resistance and lightning current amplitude. Meanwhile, the drawbacks in current lightning parameters measurement method, such as large workload to obtain data, easy misjudgment, are overcome in our work. The method provides theoretical reference for analysis of lightning protection on transmission lines.
