Against transformers impulse tests,the paper presented neutral point current,function of transmission and joint time-frequency analysis methods for fault discrimination.
针对变压器冲击试验,提出了中性点电流法、传递函数法和联合时频分析法等3种故障诊断方法。
The two standard tests are the power frequency and 1.250s impulse wave withstand tests.
两种标准试验是工频耐压试验和1.2／50s冲击耐压试验。
