摘要
因检查新投运的变压器的保护 ,发现电流、电压相序接反 ,差动保护向量错误。因此新投运变压器必须经过变压器空载检查、带负荷检查 ,并检查差动保护是否正确。
While checking transformer protection finding that the phase of current and voltage is often oppositing conneted.It is required to examine No-load and load-carring transformer to see if differetial protection act correctly,and the correct motheds are introdnced.
