Which risk increases with capacitive energization of unloaded power transformers?

💡 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.
