摘　　要：本文对电力变压器在各种激磁情况下的励磁电流的计算公式作了介绍,同时也对变压器局部放电试验的两种接线进行了讨论。基于讨论的结果,提出了一种新的更适合现场大型电力变压器局部放电试验接线。In this paper, a calculating formula of excitation current in large power transformers is introduced under various conditions. Two kinds of connection for power transformers partial discharge test are discussed as well. Based on discussion resrultes, a new connection that is more suitable to partial discharge test on site of large power transformers is presented.
