Temperature received special attention, as it clearly affects PDIV. Additionally, the PDIV models found in the literature were reviewed. Considering that the winding of the electric motor can reach 180 ∘ C during operation, the experiments were performed at high temperatures in order to evaluate the performance of PDIV models. Several models were studied regarding their accuracy at high temperatures and the advantages and disadvantages of each one were identified. Based on the analysis, a simple analytical model to estimate the PDIV of twisted pairs depending on the temperature was proposed. All in all, the proposed model was the best compromise between computational requirements and PDIV estimation accuracy at high temperatures. Finally, future lines were identified. Further studies are necessary that consider the humidity, rise time, and pulse width effect on PDIV. Moreover, new models regarding both, environmental and waveform characteristics are necessary to accurately estimate PDIV. Extended volume–time theory seems to be a good basis for that. 2076-3417 https://katalogoa.mondragon.edu/janium-bin/janium_login_opac.pl?find&ficha_no=171664 https://hdl.handle.net/20.500.11984/6034 Electric motors electric motor insulation insulation degradation Partial Discharge (PD) Partial Discharge Inception Voltage (PDIV) electrical stress environmental stress PDIV model ODS 11 Ciudades y comunidades sostenibles ODS 13 Acción por el clima Study of Partial Discharge Inception Voltage in Inverter Fed Electric Motor Insulation Systems
