全高調波歪（ぜんこうちょうはひずみ、英: total harmonic distortion 、THD）あるいは全高調波歪率とは信号の歪みの程度を表す値（あたい）。高調波成分全体と基本波成分の比で表す 。単に歪率（ひずみりつ、英: distortion factor ）とも呼ぶ。 Research, in general, on harmonic distortion aims at characterizing the distortion, the behaviour of the loads and the power system. Also the effects the distortion has on loads, the system and the environment are studied. The research presented in this thesis concerns the sources of distortion (loads) and the interaction between those and the Harmonic distortion components found in the output spectrum indicate nonlinearities inherent in the device under test. However, the measured distortion values depend on the spectral properties of the stimulus. Total harmonic distortion better (less) than 10 %; and d. Frequency control better (less) than 0,1 %.

Total harmonic distortion (THD) of portable generators. I’m looking for some insight on the total harmonic distortion (thd) metric for portable generators. I currently own a new Westinghouse WH7500E Generator which is 7500 continuous watts and 9k peak watts. However, it has come to my attention that it has a 9% thd.

These 2 single generators can be ran parallel to provide 6,000 watts of starting power and 5,500 watts of running power. This 7500W generator has major THD ( Total Harmonic distortion) propably around 25% vs less than 5% that it should have which makes your LED and Fluorescent lights flicker, which drives you crazy, and it may affect your sensitive electronics. Had other generators on the same circuit with no issues.

Equation 4 expresses this phenomenon.

(Thus the 9% Total Harmonic Distortion figure). The voltage is still 120 and the frequency is 60, just the exact waveform is distorted from a "perfect" sine wave. As far as 95% of the stuff in your house, it won't notice the difference. The magnitude of voltage distortion due to non-linear currents is mainly determined by the impedance of the system and levels of fault current and harmonic current.

Few key points: The system is micrconcontroller (TI, C2000, dual-CPU) driven electronic THD stands for Total Harmonic Distortion and can be used to estimate the degree to which a system is nonlinear.

I spoke with my contact at Firman and he said that the 10,000 Watt Portable Generator # 333-H08051 has a total harmonic distortion of 25 percent, which is 

This index can be calculated for either voltage or current: where Mh is the root mean square rms value of harmonic component h of the quantity M. r = thd(x) returns the total harmonic distortion (THD) in dBc of the real-valued sinusoidal signal x.The total harmonic distortion is determined from the fundamental frequency and the first five harmonics using a modified periodogram of the same length as the input signal. You calculate the first 200A of neutral current at 100%. For all resistive loads on the neutral exceeding 200A, you must apply a demand factor of 70%. Then, you add this value to the first 200A, which we calculated at 100%. And Understanding Total Harmonic Distortion (THD) in Power Systems - Technical Articles.
