【摘要】 提出了一种用功率转向法判断电能表接线的原理,据此原理设计出了采用单片机实现的电能表错接线判定仪。该装置能指示相序和电能表接线方式。追补电量的计算公式也能纠正错误的电能表接线方法。更多还原

【Abstract】 A turing way used to find the wiring of electrical energy meter was presented. On the basis of this theory, a device was designed to find the wrong wiring of electrical energy meter based on the single chip microcomputer. This device could indicate the vector sequence and find the connection form, give the formulation updated electrical energy, and also verify the way of the wrong connection.更多还原
