Medium-voltage (MV) or high-voltage power generation systems are designed for large-scale energy requirements where low-voltage systems reach their practical limits.
Typically, these systems are preferred in applications where power capacity exceeds 4000 amperes or where energy must be transmitted over long distances efficiently and safely.

Medium voltage configurations are commonly used for single generators above 2.5 MVA or parallel systems above 2 MVA, offering an optimal balance between cost, performance, and safety.
