Test: Distribution Systems, Cables & Insulators of Power Systems - Question 5

Match List-l (Type of Cables) with List-ll (Operatng Voltages) and select the correct answer using the code given below the lists: 

Test: Distribution Systems, Cables & Insulators of Power Systems - Question 6

Consider the following statements:
1. AAC (All Aluminium conductors) are universaly employed for feeders as well as distributors.
2. The conductor size for a feeder is mainly governed by the permissible voltage drop in the line.
Which of the above statement(s) is/are true?

Detailed Solution for Test: Distribution Systems, Cables & Insulators of Power Systems - Question 6

ACSR conductors are universally employed for distribution systems (feeders as well as distributors), AAC can be used for distribution purpose provided the spans are small.
Hence, statement-1 is false.
The conductor size for a feeder is mainly governed by current carrying capacity and overall economy. Hence, 2 is also a false statement.
