Question

The requirement of copper and steel is reduced in
25 kV, 50 Hz, single-phase AC system as compared
to DC system because of​

Answer 1

Answer:

sorry I don't know the answer

Answer 2

The requirement of copper and steel is reduced in 25 kV

Explanation:

low current

• The problem is from the traction system here we have to complete the sentence.
• Single-phase electric power is the distribution of alternating current electric power use a system in which all the voltages of the supply vary.
• In DC system generally used voltages are $1500$ V and $3000$ V but in $25$ kV AC traction system voltage is more so ​​low current.
• The answer is because of low current copper and steel requirement is less in $25$kv AC system.
