THD (Total Harmonic Distortion) refers to the distortion factor. It indicates the relationship of the harmonic components of an oscillation to the fundamental oscillation.
The ripple control signal U is a voltage (200ms measured value) measured at a carrier frequency specified by the user. Only frequencies below 3kHz are considered.
The ripple control signal I is a current (200ms measured value) measured at a carrier frequency specified by the user. Only frequencies below 3kHz are considered.
A zero sequence component can only appear if a summation current can flow back via the neutral conductor.
The K-factor describes the increase in eddy-current losses when exposed to harmonics. If the transformer has a sinusoidal load, the K-factor = 1. The larger the K-factor, the more harmonics a transformer can be exposed to without overheating.
The fundamental oscillation-reactive power is the reactive power of the fundamental oscillation and is calculated using Fourier analysis (FFT). Voltage and current do not have to be sinusoidal. All reactive power calculated in the device is fundamental oscillation-reactive power.
