The term smart meter often refers to an electricity meter, but it also may mean a device measuring natural gas, water or district heating consumption. [1] [2] More generally, a smart meter is an electronic device that records information such as consumption of electric energy, voltage levels, current, and power factor.
Using a PMU, it is simple to detect abnormal waveform shapes. A waveform shape described mathematically is called a phasor.. A phasor measurement unit (PMU) is a device used to estimate the magnitude and phase angle of an electrical phasor quantity (such as voltage or current) in the electricity grid using a common time source for synchronization.
Remote patient monitoring (RPM) is a technology to enable monitoring of patients outside of conventional clinical settings, such as in the home or in a remote area, which may increase access to care and decrease healthcare delivery costs.
The meter communicates to its collection point using 900 MHz mesh network topology. Automatic meter reading (AMR) is the technology of automatically collecting consumption, diagnostic, and status data from water meter or energy metering devices (gas, electric) and transferring that data to a central database for billing, troubleshooting, and ...
Monitors consist of a measuring component and a display component. Electricity use is measured with an inductive clamp placed around the electric main, via the electric meter (either through an optical port, or by sensing the meter's actions), by communicating with a smart meter, or by direct connection to the electrical system. Some, but not ...
The target for fitting a smart meter in every British home might be missed even after being extended twice, analysis suggests. Experts at Cornwall Insight, a consultancy, said it was unlikely that ...
This standard and command system that provides for not only smart meters and related data but for general purpose extension to other smart grid devices. ETSI TS 104 001 is an updated version of the application layer specification that incorporates enhanced security features, including AES 128 encryption, and replaces the previously ETSI GS OSG ...
Meter data management (MDM) refers to software that performs long-term data storage and management for the vast quantities of data delivered by smart metering systems. This data consists primarily of usage data and events that are imported from the head-end servers managing the data collection in advanced metering infrastructure (AMI) or automatic meter reading (AMR) systems.
