Participation reward: 2 Wealth. Reward for correct answer: 9 wealth. Judgment: In the normal operation of a low-current grounding system, there is a voltage of 100V at the open delta connection of the secondary auxiliary windings of a three-phase five-column voltage transformer.
During normal operation of a low-current grounding system, a voltage of 100 V exists at the open delta connection of the secondary auxiliary windings of the three-phase five-column voltage transformer. (×)
During normal operation of a low-current grounding system, a voltage of 100 V exists at the open delta connection of the secondary auxiliary windings of the three-phase five-column voltage transformer. Wrong, the voltage is zero
