WebSep 23, 2015 · The Total Harmonic Distortion, or THD, of a generator determines the potential for problems with high-end electronics or those considered sensitive when the power goes out. The higher the THD, the higher the potential for damage. The fact is that generator power is not the same grade as utility power. WebHigh levels of Total harmonic distortion can cause significant problems for sensitive equipment, including audio systems. It can also reduce the efficiency of electrical systems, leading to increased energy consumption and reduced overall efficiency.
