Ending index or upper bound: 50
What this part means
This label says where the repeated addition, multiplication, or accumulation stops. It sets the last term or end of the range.
Its job in the formula
50 appears in the bound of this sum. The bound states where the repeated operation starts, ends, or which values it includes.

The passage around this formula
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…
