Supraharmonics in Modern Power Grids: A Power Quality Challenge
Supraharmonics, high-frequency disturbances between 2 kHz and 150 kHz, are an emerging power quality challenge in modern grids driven by widespread use of power electronic devices such as EV chargers and inverters. Unlike traditional harmonics, they are non-synchronous and harder to measure, yet can cause significant voltage distortion, equipment stress, and system instability. Addressing them requires advanced measurement tools, deeper analysis, and new standards.
