Transfer Capability & ATC

Thermal Limit

▶  Practice Flashcards

Definition

The maximum amount of electric current a transmission conductor or equipment (such as a transformer) can carry continuously without exceeding safe temperature ratings and risking physical damage. Thermal limits protect transmission infrastructure from overheating, which can cause conductor sag, insulation failure, and uncontrolled outages. Exceeding short-term emergency ratings can cause permanent damage.
