In this paper we detail the TRE D meter, a tool for monitoring the power and the utilization of networked devices. Our solution is based on standard measurements and data export methods. The TRE D meter provides graphed energy consumption and load information of each measured device. After detailing the TRE D meter architecture, we report the main results that we have obtained by collecting mea...

Automatic Meter Reading (AMR) is the remote collection of consumption data from customer’s utility meters over telecommunications, radio, power line and other links. AMR provides water, electric and gas utility−service companies the opportunities to streamline metering, billing and collection activities, increase operational efficiency and improve customer service. Utility company uses technolo...

It is easy to measure energy consumption with a power meter. However, energy savings cannot be directly computed by the powers measured using existing power meter technologies, since the power consumption only reflects parts of the real energy flows. The International Performance Measurement and Verification Protocol (IPMVP) was proposed by the Efficiency Valuation Organization (EVO) to quantif...

With the electric industry undergoing change, increased attention is being focused on power supply reliability and power quality. Power providers and users alike are concerned about reliable power, whether the focus is on interruptions and disturbances or extended outages. Monitoring can provide information about power flow and demand and help to identify the cause of power system disturbances....

The design of compact and lightweight power transmission devices was studied for specialized high power applications, including airborne with operating voltage fixed at 270 Volts and less than 30 meter length conductors. Only commercial-off-the-shelf components were considered for the design. It was found that by using superconducting wires operated at cryogenic temperatures instead of Cu condu...

Background: Despite the increase in the use of low-level laser therapy (LLLT), there is still a lack of consensus in the literature regarding how often the equipment must be calibrated. Objective: To evaluate the real average power of LLLT devices in the Greater São Paulo area. Methods: For the evaluation, a LaserCheck power meter designed to calibrate continuous equipment was used. The power m...

We present a new approach to evaluation of Cyber Security in Power Systems using the method of modeling the power systems Infrastructure using software agents. Interfaces between module and the home smart meter are recognized as the primary points of intrusion. Keywords—Power Systems, Modeling and Simulation, Agent systems.

The Venturi meter is a straightforward pipeline device used for the metering of gas and liquids. This article presents a brief summary of the creation and characterisation of the modern Venturi meter, including the historic development of public domain algorithms to derive two phase (gas and liquid) flow rates from differential pressure measurements. The use of Venturi meters in multiphase oil ...
