Frequency analysis and calculation of transformer neutral DC caused by metro stray currents

Metro stray currents flowing into transformers can lead to high-level transformer neutral direct current (TNDC). Since the TNDC is not constant and varies with time randomly, the frequency characteristics of TNDC are confusing and unclear, which will lead to complex transformer electromagnetic chara...
