Description of Harmonic Filter Function b Harmonic Filter Function (Only Available in the 30032A) 1. What is a Harmonic? Waveform Image Harmonic refers to sinusoidal quantity having a frequency that is an integral multiple of the fundamental frequency (for example, the commercial frequency). When a harmonic is superimposed on the fundamental frequency, the waveform is distorted. Fundamental frequency 2. Why is it Necessary to Accurately Measure the Leakage Current of the Fundamental Frequency (Commercial Frequency)? One problem when measuring the leakage current to check the isolation of electrical...
