    Sep 01, 2019The leakage reactance of converter transformers is generally higher than that of AC power transformers. A leakage reactance of 0.1 p.u. is attractive economically and limits the reactive power losses which affect the converter P-Q capability, but fault considerations necessitate a modest increase, ranging practically from 0.15 p.u. to 0.18 p.u [ 61 , 130 , 131 ].
