Abstract
Direct current through directly-grounded neutrals of nearby AC transformers may induce DC biases of transformers when high voltage direct current transmission (HVDC) system operates on ground return mode, thus producing negative impact on the AC system. This paper introduced the influence of DC bias to transformer and its research efforts. The suppression measures of DC bias were analyzed .
