30 km
50 to 80 km
Given: For single phase AC locomotive, typical values for distance between sub-stations
For single phase AC locomotive, typical values for distance between sub-stations
Distance = 3โโ Vโ cos(ฯ)Pโis not applicable here as it is related to power transmission. Instead, typical distances are based on standard practices.
Understanding the context
The question is about the typical distance between sub-stations for single phase AC locomotives, which involves understanding standard practices in electric traction systems.
V=IR
Identifying standard distance ranges
For single phase AC systems used in locomotives, the distance between sub-stations is typically based on the power transmission requirements and the capacity of the system to supply power without significant loss. The options given are 50 to 80 km, 3 to 5 km, 15 km, and 30 km.
P=RV2โ
Selecting the appropriate range
Considering the context of single phase AC locomotives and typical power transmission distances, the range of 50 to 80 km is commonly associated with the spacing of sub-stations to ensure efficient power supply without excessive line losses.
3โโ V
A is correct because the distance between two sub-stations for single phase AC locomotives typically ranges from 50 to 80 km.
Understanding the principles of electric traction and power transmission is crucial for determining the appropriate distance between sub-stations, which also relates to topics like power systems and electrical engineering principles.
