Which consequence results when a hydroelectric plant's turbine experiences runaway speed?

💡 Explanation

Runaway speed causes excessive generator output voltage via electromagnetic induction, potentially exceeding the dielectric strength of insulation leading to breakdown, because voltage increases exponentially with rotational speed. Therefore over-voltage results, rather than temperature increases or environmental effects on water quality.
