- Definition system used in electrical engineering to express values of voltages, currents, powers and impedances in a power system in terms of a defined base quantity Reference "COM-Term. Coord., based on:- Mississippi State University, The Per-Unit System http://www.ece.msstate.edu/~donohoe/ece3614per_unit_system.pdf [14.1.2014]- MathWorks, Per Unit System of Units http://www.mathworks.nl/help/physmod/sps/powersys/ref/per-unit-and-international-systems-of-units.html [14.1.2014]"
- Comment In the per-unit system, any quantity (voltage, current, power, impedance) is defined as follows:per unit value (pu) = actual quantity (SI units) / base quantity (SI units)The per-unit value is indicated using 'pu'.
