    Understanding test result of 3 winding transformer

    Dear PRC, Is the formula applicable for any type of LV1&LV2 winding arrangement? Is it applicable for LV1 & LV2 axially in stack? Thanks, Fouad

    Zero Sequence current at YNd transformer

    Thanks for the answer sir. How about non radially connected? It is mean there is a SC source both from LV&HV system. In this case is there Zero sequence current inside Tranformer? Thanks

    Zero Sequence current at YNd transformer

    Hi All, I have a question regarding transformer short circuit current analysis. I want to calculate the current through inside YNd Transformer during 1phase to ground short circuit at the LV side (Delta) of the transformer. My question : is there any zero sequence current through inside the...

    Basic concept of mutual flux in Transformer

    Can anyone explain about basic understanding of transformer, why is core mutual flux remain constant when load current is increasing, while the leakage flux will increase following the increasing of the current? Thanx Fouad

    The BH curve - For the H, what does the 'ampere' in ampere-turns per meter refer to?

    Hi prc,for very large transformer with high magnetizing flux density, could this additional leakage flux make the core saturate?
