Power losses in the three‐phase three‐limb transformer due to common and differential mode of dc‐bias
Abstract Geomagnetically induced currents (GICs) and the converter modulation effect are the two main causes for dc magnetisation in power transformers. It is well known that a small dc‐bias can saturate a large transformer and thereby generate high unbalanced magnetising currents, imposing a seriou...
