2. Electricity meter - Wikipedia

   en.wikipedia.org/wiki/Electricity_meter

   North American domestic analog 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.

3. Data collector - Wikipedia

   en.wikipedia.org/wiki/Data_collector

   The EAC is initially provided by the supplier, and thereafter forecast based on actual meter readings. Data from the Data Collector (EAC/ AA's) is provided to the non-half-hourly data aggregator, which aggregates the individual values provided into a single figure split in a number of ways e.g. geographically or by supplier.

4. Electrical measurements - Wikipedia

   en.wikipedia.org/wiki/Electrical_measurements

   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 ...

5. Charge density - Wikipedia

   en.wikipedia.org/wiki/Charge_density

   In electromagnetism, charge density is the amount of electric charge per unit length, surface area, or volume. Volume charge density (symbolized by the Greek letter ρ) is the quantity of charge per unit volume, measured in the SI system in coulombs per cubic meter (C⋅m −3), at any point in a volume.

6. Electrical resistivity and conductivity - Wikipedia

   en.wikipedia.org/wiki/Electrical_resistivity_and...

   [1] [2] [3] For example, if a 1 m 3 solid cube of material has sheet contacts on two opposite faces, and the resistance between these contacts is 1 Ω, then the resistivity of the material is 1 Ω⋅m. Electrical conductivity (or specific conductance) is the reciprocal of electrical resistivity. It represents a material's ability to conduct ...

7. Maximum demand indicator - Wikipedia

   en.wikipedia.org/wiki/Maximum_demand_indicator

   Maximum Demand Indicator (MDI) is an instrument for measuring the maximum amount [clarification needed] of electrical energy required by a specific consumer during a given period of time. [1] MDI instruments record the base load requirement of electrical energy .

8. Kill A Watt - Wikipedia

   en.wikipedia.org/wiki/Kill_A_Watt

   The Kill A Watt (a pun on kilowatt) is an electricity usage monitor manufactured by Prodigit Electronics and sold by P3 International. It measures the energy used by devices plugged directly into the meter, as opposed to in-home energy use displays, which display the energy used by an entire household

9. ANSI C12.19 - Wikipedia

   en.wikipedia.org/wiki/ANSI_C12.19

   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 ...
