Why all transmission lines are AC, not DC line?..

Answer / rated kuldeep

AC transmission is used as compared to DC because for
following reason... AC can be transformed to low current
high voltage configuration using transformer. Conductor size
required will be less and hence more economical...... 2nd
reason which is main reason is AC is bidirectional hence has
ability to move in both the directions ...

DC can be transformed according to need but costly
rectifiers are neede heence for buulk power transmission ac
is used... correct me if wrong.....

Why all transmission lines are AC, not DC line?..

Answer / tarun aggarwal ymca

all line are ac because earlier it is economical to gernate convert voltage at higher level only using transformer.since in transmission require high voltage that why maximum line are ac in transmission but now a days seeing importance of dc and due to power electronic we convert dc volatage at high voltage..so hvdc is used

Why all transmission lines are AC, not DC line?..

Answer / thanigai1984

normally most of the equipments are used as AC. for
ecnomical reason.. we need inverter to change DC to AC.. in
all area .. so For long Transmission only we Transmitted DC
power...

ie DC is less transmission loss compared to AC .. but we
cant utlise the power with out inverter..
