| Abstract: | On the basis of the feature analysis made on the magnetic potentiometer, the automatic measurement of heavy A. C. Current using a magnetic potentiometer as sampling component is discussed. The schematic diagram of the measurement system is given. The working principle of the integrator, accurate rectification circuit, multifunction A/D converter as well as the display in the system is described. The experimental results show that the system is of good linearity, and the measurement accuracy reaches 0. 5 %. |
