This study introduces the development of a sub meter at the Electrical Measurement Lab of BMS College of Engineering in Bengaluru India at a location that, constitutes one of the several nodes on a distribution feeder in the first floor of a seven storey building. The system, monitors the behaviour of various electrical parameters during the operation of different types of loads connected to the three phases of the node under consideration. The three phase voltages and currents are sensed in

An effective strategy using Arduino platform for dynamic data transmission to cloud storage and a web-based Graphic User Interface brings in the graphical visualization of the operational status of the loads and the consumption cost from any remote location. Several such units are planned at various nodes and the data of each would aggregate to measure the total consumption at the secondary of the distribution transformer feeding the building. A prototype of one such typical unit developed is presented here.
