In a corner-grounded delta system, what is the grounded conductor commonly referred to as?

• A. Ground leg
• B. Dead man's leg
• C. Neutral line
• D. Safety conductor

Answer: (B)

In a corner-grounded delta system, the grounded conductor is commonly referred to as the "dead man's leg." This term specifically denotes the phase conductor that is connected to the ground at one corner of the delta configuration. Its function is significant, as it provides a reference point for the other phases in the system and helps with fault protection. In this system, the grounded conductor can limit the voltage to ground of the ungrounded phases during a fault, enhancing the safety and stability of the electrical system. The other terms, while they may relate to electrical concepts overall, do not accurately describe the grounded conductor in this particular context. For example, "ground leg" and "neutral line" refer more generally to grounding practices in other types of systems, while "safety conductor" could imply a broader notion of safety but does not specifically relate to this application within a corner-grounded delta system.
