Electronic Energy Meter Based on a Tunnel Magnetoresistive Effect (TMR) Current Sensor

Abstract: In the present work, the design and microfabrication of a tunneling magnetoresistance (TMR) electrical current sensor is presented. After its physical and electrical characterization, a wattmeter is developed to determine the active power delivered to a load from the AC 50/60 Hz mains line. Experimental results are shown up to 1000 W of power load. A relative uncertainty of less than 1.5% with resistive load and less than 1% with capacitive load was obtained. The described application is an example of how TMR sensing technology can play a relevant role in the management and control of electrical energy.

Development of ARM processor based electricity theft control system using GSM network

Abstract: Electricity theft is a common practice in developing countries which cannot be controlled by the governments due to lack of technology Emerging trends such as Automatic Meter Reading (AMR) eliminate the need of person visiting each house but this advancement further increases Non-Technical losses (NTL) because of no regular inspection at the residence However traditional meter reading by human operator is inefficient to meet the future residential development needs This paper proposes a new system based on ARM-Cortex M3 processor to protect the energy meter from phase line bypassing, neutral line disconnection, whole meter bypassing and meter tampering A SMS automatically send to utility server through Global System for Mobile (GSM) network when these measures detected In this paper a novel method is proposed to solve the problem with AMR systems without affecting its major advantage of remote monitoring Integrating this new feature into smart meters provides a robust metering solution

Methods and apparatus for metering energy consumption

Abstract: The present invention, in one embodiment, is a method for metering energy consumption with an electric meter (100). The method includes steps of: generating metering quantities (202) for a plurality of phase voltages from a multiphase voltage source (102), including generating revenue-related data (110); monitoring voltage changes on at least one of the phase voltages; and performing a predetermined task in response to a voltage change on at least one of the phase voltages while continuing to generate revenue-related data (110).

Automated Topology Discovery and Management for Electric Meters

Abstract: A method for automated topology discovery and management of meter nodes in a power grid is described. In the discovery mode any of the meter nodes is able to act as a proxy for a data concentrator to sort out the topology, and to determine the best path for communicating between a concentrator and each of the meter nodes.
