Energy meter with PLC communication

By Michal Szalbot


Our thesis is about development of equipment, which combine two technology. First technology is wattmeter which is used to energy measurement and second is Power line communication. Wattmeter needs two variables for measurement, voltage and current. Voltage measurement is less difficult than measurement of current. Voltage can be reduce and measured by A/D converter. Current has to be transform to voltage and than can be measured same way. To do that we use current transformer. Than we design program for the microcontroller, involvement and PCB. Wattmeter is connect to PLC modem which has been chosen. Fusing this two technology we create wattmeter network. Next step was program which is used to network control and data collecting. This data are used to create charts in web application
