A 33kV medium voltage feeder line can stretch up to an average of how many kilometers?
A. 50km
B. 80km
C. 150km
D. 200km
Answer (2)
Analyze the typical range of a 33kV medium voltage feeder line (50-100 km).
Compare the given options (50km, 80km, 150km, 200km) with the typical range.
Determine that 80km is the closest and most reasonable answer.
Conclude that the average maximum length is \boxed{80km}.
Explanation
Problem Analysis A 33kV medium voltage feeder line typically stretches up to an average of 50-100 kilometers. We need to compare this range with the given options to determine the closest match.
Analyzing Options Let's analyze the options:
A. 50 km: This is within the typical range. B. 80 km: This is also within the typical range. C. 150 km: This is significantly higher than the typical range. D. 200 km: This is also significantly higher than the typical range. E. None of the above: This option is selected if none of the provided options are close to the typical average.
Determining the Best Fit Since both 50 km and 80 km are within the typical range, we need to determine which one is a better fit. Without more specific information, it's reasonable to assume that the average length falls somewhere between these values. However, since the question asks for 'up to an average', we should consider the higher end of the typical range. A value of 80km is a reasonable average maximum length.
Selecting the Answer Given the options, 80km is the closest reasonable answer.
Examples
Understanding the average reach of a medium voltage feeder line is crucial for planning and designing electrical distribution networks. For example, knowing the typical length helps engineers determine the optimal placement of substations to minimize power loss and maintain voltage levels within acceptable limits. This also aids in cost estimation for materials like cables and support structures, ensuring efficient and reliable power delivery to consumers. Proper planning prevents voltage drops and ensures stable electricity supply, which is vital for residential, commercial, and industrial needs.
A 33kV medium voltage feeder line typically stretches up to an average of 50-100 kilometers. Among the options given, 80 km is the closest and most reasonable average maximum length. Therefore, the chosen option is B. 80 km.
