A harmonic analyzer is an essential instrument used to measure and analyze the harmonic content of electrical signals in power systems. Harmonics are voltage or current waveforms that are integer multiples of the fundamental frequency and can cause various issues in electrical systems, including overheating, equipment malfunction, and reduced efficiency.Harmonic analyzers measure the amplitude and phase of harmonics present in the electrical signal, typically focusing on the first few harmonic orders (up to the 50th or higher).
