摘要
介绍采用倒推法计算供电器的馈电级数以及通过降低回路电阻提高供电级数的方法 ;描述影响供电器馈电级数的主要因素 ,以及如何估算供电器实际功耗 ,及时发现传输过程中的偷漏现象。
Introduces the method that calculates the power supply appliances' series from the end and increase the power supply series by lowering return resistance. Describes the main factors that influenced the appliances power supply's series, and how to compute the actual power of electric appliances, and avoid the eletric stealing or the electric leakage phenomenon during transmission.
