What is the voltage between any two hot lines of a 230-volt grounded delta power supply?

• A. 0V
• B. 115V
• C. 230V
• D. 240V

Answer: (C)

In a 230-volt grounded delta power supply, the voltage between any two hot lines is indeed 230 volts. This is because in a delta configuration, each hot line is connected to one another in a closed loop, effectively creating a system where the voltage maintained across any two wires represents the full line voltage of the system. The grounded delta setup means that one of the phases is connected to ground, helping to stabilize the system and provide a reference point for the voltage readings. However, this grounding does not affect the voltage measurement between the hot lines. Therefore, the voltage between any two of the three hot lines in this configuration remains at 230 volts, which is why this value is identified as the correct answer.
