Most Dranetz Power Quality products can also compute and measure common energy parameters, such as W, VA, VAR, PF, Demand, Energy, and more. The ability to measure energy in addition to PQ opens the doors to many more applications, including energy only applications that can include electrical consumption.
When measuring electrical consumption for billing, revenue, meter verification, reference, or other purposes, high accuracy is often required. When the metered data is to be used for billing purposes, a revenue certified/grade meter may be required by code or law. When a revenue certified meter is not required, a revenue accurate meter may meet the needs of the application. Such a meter has similar accuracies as a revenue certified meter, but without the laboratory testing and the certification itself.
This White Paper summarizes the most common standards used for revenue certified energy metering and how the accuracies and capabilities of current Dranetz products compare to these standards.
