a) Feeders are designed from the point of view of its current carrying capacity.
b) Distributors are designed on the basis of voltage drop in it.
c) Voltage variation at the consumers terminal is not considered while designing the distributor.
Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDFThe correct answer is option 2):((a) and (b) only)
Concept:
- A feeder is a conductor having constant current density. The size of the feeder is designed based on current-carrying capacity. For V ≤ 220 kV, the selection of conductor is done based on the current-carrying capacity.
- The main criteria for the design of a feeder are its current carrying capacity which accounts for thermal limits rather than voltage drops.
- A distributor has variable loading along its length due to the service conditions of tapping by the individual consumers. The voltage variation at the consumer end must be kept under ±5%. So, the main criterion for the design of a distribution feeder is voltage regulation or voltage drop.
- Hence c) Voltage variation at the consumer's terminal is not considered while designing the distributor is wrong
