The stator assembly receives a quick , high - voltage surge test ( approximately 2500 volts peak ) to each phase in sequence , and the decay of the surge through the windings is integrated by the tester and compared phase to phase 對于定子總成進行逐個相位的快速、高壓(峰值約為2500伏)的沖擊波試驗,并且測試員對通過線圈的沖擊波的衰減進行完全的測試,進行相位與相位的比較。
