Thermal Design of Prefabricated MV/LV Substations

This document discusses the thermal design and numerical modeling of prefabricated MV/LV substations, focusing on temperature-rise testing as per IEC 62271-202 standards. It explains the three types of heat transfer (convection, conduction, radiation) and how numerical simulation can optimize substation architecture, validate customer adaptations, and reduce reliance on empirical extrapolation.
