How do meters mediate? Energy meters, boundary objects and household transitions in Australia and the United Kingdom

Abstract: This paper investigates the changing role of an integral but often overlooked technology within our energy systems: the meter. Empirical cases from the United Kingdom and Australia demonstrate the repurposing of the energy meter. No longer just an instrument of metrology, the meter is increasingly seen by utilities and governments as a key enabling technology for a raft of objectives, from tariff reform to peak load reduction. We draw on the Science and Technology Studies concept of a boundary object to explore these changes. A boundary object is conceptualised as positioned between different social worlds – such as those of householders, government, and utilities – and as having sufficient interpretive flexibility to mediate between their distinct interests. Here we use the boundary object concept to explain the ways in which the meter is being reconfigured, and in particular to analyse the role of householders in the transition to digital meters.

Demo: In-situ Power Consumption Meter for Sensor Networks supporting Extreme Dynamic Range

Abstract: Typical wireless sensor devices feature an extreme power consumption range between their active and sleep states, thus requiring different hardware setups for measuring their expenditure with high accuracy. In this demo paper we present the NITOS dynamic ACM, an in-situ power meter that exploits auto-ranging methods to support high dynamic currents. Our implementation features 250 kSps of sampling rate, while attaining high precision in both the active and sleep states of the targeted device, by using two different shunt resistors that are alternated automatically with the aid of a high speed comparator. The acquired results indicate the smooth performance of our system as well as the high accuracy attained.

Design and implementation of remotely located energy meter monitoring with load control and mobile billing system through GSM

Abstract: Electricity, the most usable form of energy is used widely through the whole world. With the evolution of modern technology, the usage of electricity is escalating gradually. But the production of electricity is confined due to deficiency of resources. So power must be used in a concise way. In many countries, electrical energy is measured by energy meter which is inspected by a human. According to their inspection, the electric bills are prepared and most often these are prepared on the basis of assumption which could be inaccurate, costly, time-consuming as well as error prone. Due to the absence of regular monitoring system, sometimes consumer use electrical energy month after month without paying any bill. Energy meter monitoring and digital billing system is a kind of system which would be able to avoid traditional meter reading, save human resources, improve the accuracy and prevent the power theft. In this paper, a remote monitoring of energy meter and digital billing system is inaugurated through GSM 900. For monitoring server, major programming languages had been introduced to relate the methodologies, execute logical functions, store data in a database and send the monthly bill to the consumer cell phone number and finally disconnect the unpaid consumer.

Techno economic analysis of smart meter reading implementation in PLN Bali using LoRa technology

Abstract: Traditional electricity meters read manually, large workloads, major errors and distributed at different installation locations, need to spend a lot of time and labor costs In real-time, the accuracy and extension of the application cannot be fulfilled With technological developments, electric meters now can be used both ways, for real-time remote reading, and can be used as prepaid and postpaid, making it smart meter Currently the smart meter has become an important part of the smart grid system Therefore, the national power utility company (PLN) Bali region decided to replace the existing meter with smart meter to support Bali Eco Smart Grid Long Range (LoRa) wide area network (WAN) is the access technology that used for implementing smart meter because it has benefits including can reach long distance, low power, and lower cost This study aims to analyze the techno economic smart meter 2 ways implementation at Bali region by using techno-economic method and cost-benefit analysis In addition to analyze technological and economic aspects, the business model and the regulatory aspect analysis are also included The results show that LoRa WAN is one of the technology options that can be used today, the business model that can be used is build own or implementation is done by itself, build operate transfer (BOT) or outsourcing to third party, and rental model According the ministry of communication and information regulation number 35/2015, LoRa WAN that operate at frequencies 923–925 MHz can be implemented to support smart meter implementation by Bali PLN

Electricity stealing preventing alarm of electric meter box

Abstract: The utility model discloses an electricity stealing preventing alarm of an electric meter box, which relates to an alarm, and aims to solve problems that an exiting existing alarm device of the electric meter box can not monitor strong magnetic interference, and can not monitor on-off state of a door of the electric meter box. The electricity stealing preventing alarm comprises an electric meter box, a single chip microcomputer, a GPRS module, a door-opening sensor, a strong magnetic sensor, and a trip circuit, wherein the single chip microcomputer, the GPRS module, the strong magnetic sensor and the trip circuit are all installed in a box body of the electric meter box; the door-opening sensor is used for detecting the on-off state of the door of the electric meter box; a door-opening signal output end of the door-opening sensor is connected with a door-opening signal input end of the single chip microcomputer; an interference signal output end of the strong magnetic sensor is connected with an inference signal input end of the single chip microcomputer; an alarm signal output end of the single chip microcomputer is connected with an alarm signal input end of the GPRS module; and a switch-off control signal output end of the single chip microcomputer is connected with a switch-off control signal input end of the trip circuit. The alarm disclosed by the utility model is used for preventing electricity stealing for the electric meter box.
