Is it D.C or A.C transmission system for 132 Kv and other transmission lines?
relatively DC is used in some intense voltage transmission purposes, yet in uncomplicated terms in specific circumstances that warrant it. bijay sums up somewhat some the advantages of HVDC transmission (whether there are nevertheless corona issues purely like in AC transmission). AC transmission is better than DC transmission in quite much all situations. intense voltage DC is used quite lots in uncomplicated terms while the economics dictate that that's functional to realize this. DC has the income that fewer conductors are required than 3phase AC which would be a significant cost cost reductions. on the different hand, the AC could desire to be switched over to DC, sent down the line and then switched over decrease back to AC so as that clientele can relatively use the electrical energy, which would be a significant boost in cost (conversion kit and maintenance). So plainly when the dimensions of the transmission line is somewhat long, the cost cost reductions beat out the better costs. hence, the applying business business enterprise makes a decision to place in the needed conversion kit, strains and towers to transmit intense voltage DC. One occasion of HVDC in united statesa. may be the Pacific Intertie. that's a very long line that connects the Pacific Northwest to shoppers in southern California. It replaced into authorized in the 1960's and geared up utilizing Swedish HVDC technologies. check out the pedia articles for extra info on reward/destructive aspects of intense voltage DC transmission that I relatively have not coated.
