When vibration signal analysis method is used to monitor the transformer, the core vibration signal is often obtained as the transformer runs under no-load condition. In this paper, a method extracting core vibration signal without operating transformer under no-load condition was introduced. The transformer vibration accelerative signals at different on-load current and no-load condition were measured. From the fitted curve of on-load current versus fundamental frequency component of vibration accelerated signal, the value of fundamental frequency component was obtained when the on-load current was zero, which was almost equivalent to the fundamental frequency component of vibration accelerative signal measured under no-load condition, thus the fundamental frequency component of core vibration can be obtained by using on-load current method. The core with fault was finally monitored by using the on-load current method compared with wavelet package transform method. From the result of experiment, it can be seen this method is very useful to estimate the condition of the transformer core.
