Research on the Measurement of Household Appliance Impedance Characteristic
Abstract:
Impedance of power line channel is the most important factor for power line communication. All kinds of household appliances randomly connect or disconnect from the network, which give rise to impedance variation on power line channel. The mismatch of impedance would reduce the performance of the signal transmission. The power network is mixed with lines and loads. In order to investigate the main factors that affect power network impedance, this paper proposed a method to measure the impedance of active household appliances. Some household appliances are measured with this method, and the result shows that this method can measure the impedance effictively, which helps the study on the impedance charicteristics.
