E-ring: A Non-Invasive Electricity Consumption Monitoring System

Monitoring electricity consumption has a key role in reducing energy consumption. This monitoring can be frequent (several times per week) or continuous. Recent studies showed that such monitoring can reduce residential energy consumption by as much as 15%. The development of energy management systems in the monitoring systems and intelligent energy meters have been going for a while. In this paper, we will present a new electricity monitoring device called “E-ring”. E-ring is a non-invasive tool mainly made from a current transformer clamp meter that clamps to the main electricity cables of the user's home and measures the electrical consumption and sends the measured data to an online server and then makes it accessible from the user's mobile phone using a specially-developed mobile application. It has many advantages such as low data rate, low price, and real-time access to the consumption data and simultaneously calculate the estimated price for the household/industrial electricity bill with a tolerance of around 2%.
