← TechnologyWhich risk increases with capacitive energization of unloaded power transformers?
A)Inrush current magnitude✓
B)Insulation material breakdown
C)Core saturation duration
D)Reduced eddy current losses
💡 Explanation
Higher inrush current occurs because switching transients excite the transformer's magnetizing inductance under no-load conditions, leading to temporary core saturation. Therefore, inrush current increases, rather than insulation breakdown or reduced eddy losses, under purely capacitive energization.
