← TechnologyWhich outcome results from increased load impedance in a power distribution transformer connected to multiple residential distribution systems?
A)Elevated transformer core saturation
B)Reduced system voltage drop✓
C)Enhanced power factor correction
D)Minimised harmonic distortion
💡 Explanation
The risk of voltage sag decreases because of the reduced current requirements through the transformer under load; the mechanism involved is Ohm's Law. Therefore, with lower current, the voltage drop across the line impedance diminishes rather than increasing line losses or requiring additional power factor balancing systems.
