Which process protects a transformer under overload conditions?

💡 Explanation

A transformer's differential relay detects imbalances between currents, actuating breaker trips during overload to prevent damage because `differential protection` isolates the fault, therefore averting thermal runaway, rather than optimizing power quality directly.
