Question: A (69-mathrm{kV}) circuit breaker has a voltage range factor (mathrm{K}=1.25), a continuous current rating of (1200 mathrm{~A}), and a rated short-circuit current of 19,000 A

A $69-\mathrm{kV}$ circuit breaker has a voltage range factor $\mathrm{K}=1.25$, a continuous current rating of $1200 \mathrm{~A}$, and a rated short-circuit current of 19,000 A at the maximum rated voltage of $72.5 \mathrm{kV}$. Determine the maximum symmetrical interrupting capability of the breaker. Also, explain its significance at lower operating voltages.
