Against transformers impulse tests,the paper presented neutral point current,function of transmission and joint time-frequency analysis methods for fault discrimination.
針對變壓器沖擊試驗,提出了中性點電流法、傳遞函數法和聯合時頻分析法等3種故障診斷方法。
The two standard tests are the power frequency and 1.250s impulse wave withstand tests.
兩種標準試驗是工頻耐壓試驗和1.2/50s沖擊耐壓試驗。
