Effects of Voltage Interharmonics on Cage Induction Motors
Energies, 2021 In a power system, the voltage waveform usually contains harmonics and sometimes interharmonics, often defined as components of frequency greater than the fundamental voltage component but not of its integer multiple.

Power measurement accuracy analysis in the presence of interharmonics [PDF]
Measurement: Journal of the International Measurement Confederation, 2020 Abstract Interharmonics present in voltage/current signals affect the measurement accuracy of power quantities defined in standard IEEE 1459. In this paper, the measurement errors caused by the measurement time intervals not satisfying integral multiple periods of interharmonics are discussed.

Harmonic Phasor Estimation Method Considering Dense Interharmonic Interference [PDF]
Entropy, 2023 Due to the limitation of frequency resolution and the spectrum leakage caused by signal windowing, the spectrums of harmonic and interharmonic components with close frequencies overlap each other. When the dense interharmonic (DI) components are close to
