Discussion

Simulation and practical results show surge arrester counter performance decreases dramatically with corona modelling in transmission lines.

Surge arrester counter performance decreases from 98.6% to 4% when modelling corona is considered, underscoring its impact.
Key evidence revealed estimating surge arrester counter operation across a 400 kV transmission line in Iran using EMTP-RV software.
Simulations alongside practical results demonstrated the necessity of incorporating corona effects for accurate performance evaluation.
This work highlights the importance of precise modelling in surge arrester performance assessments, with implications for energy protection systems.

Modarresi et al. (2025) studied this question.
