Abstract: The time for direct current resistance testing of transformer lowvoltage side was too long, the reason of which was analyzed, and the solving method was put forward. It is expected that the method can be used as reference for transformer field testing of other hydropower stations.

Key words: transformer, direct current resistance, magnetization helping, constant current source, test
