Experimental Three-Phase Load-Switching Event Dataset from a Synchronous-Generator-Fed Isolated AC System

This dataset contains calibrated analysis-ready three-phase line-to-linevoltage and line-current waveform recordings and a processed event datasetacquired from a synchronous-generator-fed, three-phase, three-wirelaboratory AC system with an insulated neutral. The primary verified dataset comprises 182 load-switching events from11 complete recordings. It covers active, inductive, and capacitive loadconnection and disconnection under no-load, active-load, and inductive-loadbackground conditions. The deposit includes dataset documentation, the processed event table,and 11 verified waveform recordings with matching metadata. It supportsresearch on compact power-change descriptors, load-switching eventidentification, recording-grouped validation, and operating-backgroundtransfer in isolated AC power systems.
