INTEGRATING WATTMETER Meaning and
Definition
-
An integrating wattmeter is a specialized measuring instrument used to calculate the total energy consumption and power usage of an electrical system over a specific period. It combines the functions of an integrating device and a wattmeter to determine the cumulative energy consumption accurately.
This type of wattmeter is designed to measure real power in watts (W) and integrate it over time to obtain the total energy consumed in watt-hours (Wh) or kilowatt-hours (kWh). It operates by continuously sampling the voltage and current signals of the electrical load and multiplying them together to determine the instantaneous power. These instantaneous power values are then summed up or integrated over time to yield the total energy consumption.
The integrating wattmeter typically consists of high-precision circuitry and sensors to ensure accurate measurement of both voltage and current. It also incorporates an internal clock or timer to record the duration or time period for energy integration. Certain models may include additional features such as data logging capabilities, digital displays, and communication interfaces for data retrieval and analysis.
Integrating wattmeters find widespread applications in various fields, including residential, commercial, and industrial settings. They are commonly used for energy management, bill verification, power quality analysis, and load profiling. By providing a comprehensive measurement of energy consumption, integrating wattmeters assist in identifying efficient energy utilization patterns, optimizing power usage, and promoting energy conservation.

Etymology of INTEGRATING WATTMETER
The term "integrating wattmeter" is derived from the combination of the words "integrating" and "wattmeter".
The word "integrating" comes from the verb "integrate", which is derived from the Latin word "integrare", meaning "to make whole or complete". In the context of a wattmeter, the term refers to the measurement of integrated or cumulative electrical power over a specific period of time.
The term "wattmeter" originates from the combination of the unit of power measurement, the "watt", named after the Scottish engineer James Watt, and the suffix "-meter", which denotes an instrument used for measuring. A wattmeter is an instrument used to measure the electric power in watts in an electrical circuit.
Therefore, an "integrating wattmeter" is an instrument that measures the integrated or cumulative electrical power over time in watts.
