Why this formula appears here
The instrumentation baseline for a new site starts with IEEE 519, the North American reference for harmonic control, which frames the problem around the point of common coupling — the interface between the utility and the customer — and assigns the utility responsibility for background voltage distortion while assigning the customer responsibility for the current distortion its own equipment injects [ 7 ] . The standard’s working measure of current distortion, total demand distortion, is the root-sum-square of harmonic currents up to the fiftieth order expressed as a fraction of the maximum demand current rather than of the instantaneous fundamental: . a normalization…

This label says where the repeated addition, multiplication, or accumulation starts. Read its value or condition together with the article’s description of the index.
Read this term in its guide →Ending index or upper bound: 50
This label says where the repeated addition, multiplication, or accumulation stops. It sets the last term or end of the range.
