North American domestic analog (Ferraris disk) electricity meter. Electricity meter with transparent plastic case (Israel) An electricity meter, electric meter, electrical meter, energy meter, or kilowatt-hour meter is a device that measures the amount of electric energy consumed by a residence, a business, or an electrically powered device over a time interval.
This standard defines a table structure for utility application data to be passed between an end device and a computer. The "end device" is typically an electricity meter, and the "computer" is typically a hand-held device carried by a meter reader, or a meter communication module which is part of an automatic meter reading system. C12.19 does ...
ANSI C12.20 is an ANSI standard that describes an American National Standard for Electricity Meters - accuracy and performance. The C12.20 standard established the physical aspects and performance criteria for a meter's accuracy class. It refines certain details in ANSI C12.1 and ANSI C12.10. The existing ANSI accuracy classes for electric ...
Electricity meter, a device for measuring electricity usage Smart meter, an electrical meter that records consumption of electric energy and communicates information to the utility for monitoring and billing; Gas meter, a specialized flow meter used to measure the volume of fuel gases such as natural gas and propane; Water meter, a device for ...
Capacitance meter: Measures the capacitance component Current clamp: Measures current without physical connection Curve tracer: Applies swept signals to a device and allows display of the response Cos Phi Meter: Measures the power factor Distortionmeter: Measures the distortion added to a circuit Electricity meter: Measures the amount of energy ...
High-precision laboratory measurements of electrical quantities are used in experiments to determine fundamental physical properties such as the charge of the electron or the speed of light, and in the definition of the units for electrical measurements, with precision in some cases on the order of a few parts per million. Less precise ...
The GCP provides a common framework for communication between meters and data collection systems, ensuring interoperability across different manufacturers and devices. It defines a set of basic objects, services, and communication methods for exchanging metering data, including energy consumption, demand measurements, and meter status. [2]
Nonintrusive load monitoring (NILM), nonintrusive appliance load monitoring (NIALM), [1] or energy disaggregation [2] is a process for analyzing changes in the voltage and current going into a house and deducing what appliances are used in the house as well as their individual energy consumption. Electric meters with NILM technology are used by ...
