Participation reward: 2 Wealth. Reward for correct answer: 9 wealth. When a metallic three-phase short circuit occurs at the end of the line, the voltage measured on the busbar at the location of the protection device is ( ). A is the voltage drop along the circuit from the fault point to the location where the protection device is installed. B is the same as that at the short-circuit point. C: It cannot be determined.

B. The same as the short-circuit point. B. The same as the short-circuit point.
When a metallic three-phase short circuit occurs at the end of the line, the voltage measured on the busbar at the location of the protection device is (A, which represents the voltage drop along the line from the point of fault to the location of the protection device).
When a metallic three-phase short circuit occurs at the end of the line, the voltage measured on the busbar at the location of the protection device is (A). A is the voltage drop along the circuit from the fault point to the location where the protection is installed. B is the same as that at the short-circuit point. C: It cannot be determined.
