Application note

ST485EB for e-meter applications

Introduction
This application note explains the procedure for designing the RS-485 communication lines
in energy metering applications which helps e-meter engineers build their projects.
Energy meters are used to monitor personal usage of electricity. In the past only one kind of
e-meter was used which was an electromechanical device and required human intervention
for the periodic on site data collection. The new frontier in energy metering is a new
generation
