IEEE 1459-2000 pdf download IEEE Trial-Use Standard Definitions for the Measurement of Electric Power Quantities Under Sinusoidal, Nonsinusoidal, Balanced, or Unbalanced Conditions
1.Overview
This trial-use standard is divided into three clauses. Clause 1 lists the scope of this document, Clause 2 listsreferences to other standards that are useful in applying this trial-use standard. Clause 3 provides the defini-tions,among which there are several new expressions.
The preferred mathematical expressions recommended for the instrumentation design are marked with asign. The additional expressions are meant to reinforce the theoretical approach and facilitate a betterunderstanding of the explained concepts.
11 Scope
This is a trial-use standard for definitions used for measurement of electric power quantities under sinusoi-dal, nonsinusoidal. balanced, or unbalanced conditions. It lists the mathematical expressions that were usedin the past, as well as new expressions. and explains the features of the new definitions.
1.2 Purpose
This trial-use standard is meant to provide organizations with criteria for designing and using meteringinstrumentation.
2. References
This trial-use standard shall be used in conjunction with the following publications. If the following publica-tions are superseded by an approved revision, the revision shall apply

3. Definitions
Mathematical expressions that are considered appropriate for instrumentation design are marked with thesign . When the signappears on the right side, it means that the last expression that is listed isfavored. Each descriptor of a power type is followed by its measurement unit in parentheses
