Final answer:
The question is about grounding in a 240-kV power transmission line and the requirement of a high impedance for the grounded conductor.
Step-by-step explanation:
The given question is related to grounding in a 240-kV power transmission line.
According to the National Electrical Code (NEC) 250.24(C), grounded conductor brought to service equipment requires high impedance. This means that a resistor is typically connected in series with the grounded conductor to limit the flow of fault current.
For more specific information about the application of this code in the given scenario, please provide additional details.
