← TechnologyWhich outcome occurs when reactive power increases excessively in a power distribution system using multiple interconnected transformers operating near thermal limits?
A)Increased transformer core saturation✓
B)Decreased system frequency instability
C)Improved voltage regulation control
D)Reduced transmission line losses
💡 Explanation
Increased reactive power causes increased current flow in transformer windings because of reduced power factor, leading to core saturation. Therefore, the core saturates due to excessive magnetizing current, rather than improved performance or reduced losses under these conditions.
