← TechnologyWhich risk increases when supplying a capacitive load substantially beyond a distribution transformer's rated kVA?
A)Resonance and voltage instability✓
B)Core saturation reduces efficiency
C)Increased skin effect at the terminals
D)Decreased hysteresis losses in core
💡 Explanation
Resonance and voltage instability increase because large capacitive loads interact with the transformer’s inductive reactance to create a lightly damped resonant circuit; therefore, oscillations occur, which creates voltage instability, rather than the other options.
