Which outcome occurs when transformer impedance is abnormally low during a fault?

💡 Explanation

Low transformer impedance causes increased fault current flow because impedance limits current according to Ohm's law; therefore fault current rises, rather than decreases that would improve the system; low impedance exacerbates issues.
