In mass production of sealed lead acid battery, partial products fail because of serious open circuit voltage (OCV) loss during storage.

在某型号密封铅酸蓄电池的批量生产中，出现贮存期间部分电池因开路电压显著下降而失效的现象。

Firstly, this paper shows a method to detective the open circuit loss and the load loss of the there-phase power transformer online by operating the real-time voltage and current of the transformer.

首先，本文对三相电力变压器空载损耗、负载损耗在线检测理论进行了讨论和分析。
