IET Generation, Transmission &Distribution, Volume 19, Issue 1, January/December 2025.• Experimental Validation of the HIF Model: Laboratory data are used to model high impedance faults (HIF), considering their interaction with three different types of trees (Açaí, Bamboo and Mango). This validates the model, thereby increasing its reliability in simulations and its applicability in practical settings. • Detailed Parameterization of the
