The maximum limit is based on the ratio of ISC/IL, which is measurement of the customer's affect on the electrical distribution system.
Web17 May 2000 · Total harmonic distortion is the total power of the first N harmonics of the fundamental. THD can be expressed relative to the converter's full-scale input range (dBFS) or relative to the input signal (dBc, for "dB relative to the carrier"). Many manufacturer's simply list "dB" which isn't technically correct. WebAs the equation shows, the THD factor increases the larger the harmonics are in relation to the fundamental magnitude, i.e., the more non‑linear a signal response is. For example, a …
