3 Terms and units of measure

3.1 Harmonics [component] harmonic (component) The number of periods in the Fourier series is a component of an integer greater than one. Note. 1 In this specification, DC [component] is considered as a harmonic of the order 0. 2 See Annex A for formulae for expressions related to harmonic voltages, harmonic currents, and harmonic powers formed by them. 3 Rewrite GB/T 17215.302-2013, definition 3.4. 3.2 Harmonic Absolute Error harmonicabsoluteerror HARMONIC INDICATORS MEASUREMENT OF HARMONIC INDICATORS AND REFERENCE VALUES (THE SAME HARMONIC INDICATIONS PROVIDED BY MEASUREMENT STANDARD DEVICES) The difference between. V, mV, μV (harmonic voltage); A, mA, μA (harmonic current); or W, mW, μW (Harmonic power) is expressed. 3.3 Harmonic Relative Error harmonicrelativeerror The ratio of harmonic absolute error to the reference value. With mV/V, μV/V (harmonic voltage); mA/A, μA/A (harmonic) Wave current); or mW/W, μW/W (harmonic power), can also be expressed as a percentage. 3.4 Harmonic reference error harmonicfiducialerror
