摘要
在多功能电能表的设计中我们发现,由于对三相视在功率理解的不同,会导致视在功率和视在电能计算结果的不同。本文提出并探讨了多功能表设计中视在功率的计算方法,分析了它们的差别,并指出这种差异性是原理性的,与制造工艺无关。
The paper put forward the calculation methods of apparent power in static multi-function meter. In the process of meter design, we find that the different understanding of three phase apparent power leads to the different calculation results of apparent power and apparent energy. This difference is of principle, not from the manufacturing technology.
