The main advantage of ac. transmission system over d.c. transmission system is
(A) Easy transformation
(B) Less losses in transmission over long distances
(C) ) Less insulation problems
(D) Less problem of instability.
Answers
Answer:
Advantages: There are two conductors used in DC transmission while three conductors required in AC transmission. There are no Inductance and Surges (High Voltage waves for very short time) in DC transmission. ... A DC System has a less potential stress over AC system for same Voltage level.
C.)Less Insulation Problems

Answer:
B) Less losses in transmission over long distance.
Explanation:
The primary benefit of an AC transmission system over a DC transmission system is that
The primary benefit of an AC transmission system over a DC transmission system is that
Transmission is simple.
Long-distance transmission losses are reduced.
Insulation issues are less of a concern.
Instability is less of an issue.
The primary components of an electric power system are the generation, transmission, and distribution systems. Transmission lines link generating stations and distribution networks together. Transmission lines, in most cases, indicate the bulk transfer of power between primary load centres via high-voltage links. The distribution system, on the other hand, is primarily responsible for delivering this power to customers via lower voltage networks.
CHANGING THE CURRENT (A.C.)
An alternating current is one whose magnitude and direction change on a regular basis. It rises from zero to a maximum value, then falls to zero and reverses direction, rising to a maximum in this direction before falling to zero. A 'cycle' refers to the entire set of variants. As a result, the current flows in one direction for one-half of the cycle and in the opposite direction for the second half.
DIRECT CURRENT (D.C.)
DC current is that current that may or may not change in magnitude but it does not change its direction.
