'I'he purpose of this paper is to build a computer vision system that cndows an ant onomous mobile robot the ability of automatic measnring of the anlog and digital meters installed in nuclear power plant (NPP). In the m ~ t e r image captured by the camera, the meter area is sorted out using mainly the thresholding and the region labeling. The positions and the angles of the needles in analog ...

In this paper the authors detail the TREND meter, a tool for monitoring the power and the utilization of networked devices. Their solution is based on standard measurements and data export methods. The TREND meter provides graphed energy consumption and load information of each measured device. After detailing the TREND meter architecture, the authors reported the main results that they had obt...

In smart power grids, a smart meter placed at a consumerend point reports fine-grained usage information to utility providers. Based on this information, the providers can perform demand prediction and set on-demand pricing. However, this also threatens user privacy, since users’ specific activity or behavior patterns can be deduced from the finely granular meter readings. To resolve this issue...

Advanced metering devices (smart meters) are being installed throughout electric networks in Germany (as well as in other parts of Europe and in the United States). Unfortunately, smart meters are able to become surveillance devices that monitor the behavior of the customers. This leads to unprecedented invasions of consumer privacy. The highresolution energy consumption data which are transmit...

We describe the results of a comparison of reference standards between the National Institute of Standards and Technology (NIST-USA) and Centro Nacional De Metrología (CENAM-Mexico). Open beam (free field) and optical-fiber-based measurements at wavelengths of 1302 nm and 1546 nm are reported. Both laboratories' reference standards were compared by means of a temperature-controlled optical trap...

The electrical/power distribution and commercialization scenario is evolving worldwide, and electricity companies, faced with the challenge of new information requirements, are demanding IT solutions to deal with the smart monitoring of power networks. Two main challenges arise from data management and its smart monitoring of power networks: real-time data acquisition and big data processing ov...

We present a topology detection method combining smart meter sensor information and sparse line measurements. The problem is formulated as a spanning tree identification problem over a graph given partial nodal and edge power flow information. In the deterministic case of known nodal power consumption and edge power flow we provide sensor placement criterion which guarantees correct identificat...
