Fault Diagnosis of Power Transformer based on EMD Technology

This paper focuses on the use of EMD technology to transformer fault diagnosis. Through continuous analysis and in-depth study on large amounts of data, according to the experience and the related algorithms are derived for intrinsic mode function, this method is the EMD algorithm, namely EMD algorithm, its core algorithm is HHT transform. By this method, the data is too large and difficult to classify and analyze the case, get better intrinsic mode function (Intrinsic Mode Function, referred to as IMF). The data were analysed by IMF, can draw the fault types of transformer under different conditions.
