The vibration characteristics of converter trans-former can reflect its mechanical state effectively. Recurrence qualification analysis (RQA) reveals the nonlinear characteristics of the electrical equipment. This paper analyze the vibration characteristics of± 800kV converter transformer under load conditions including power-up, power-down, full load operation and so on through recurrence plots. Recurrence rate and determinism are analyzed in the paper, and the results show that these two vibration characteristics can be helpful for converter transformer vibration evaluation.
