why AC cannot to be stored and DC cannot be transmitted?
Answer Posted / shekhar mahajan
generally in DC supply we cant tranmitt bcas for step up &
step down vtg we required transformer but due to absence of
frequency in DC,transformer not work,then we onther option
i.e we can use converter or rectifier but they are more
costly,but for EHV tansmission line exm.+/-500v or above
than that we can use DC for transmission bcas in DC more
technical & commertial benefits such as losses & tower
structure,conducter req.
the AC reaches zero level for every half cycles the averge
voltage cannot be retained.Hence from the conventional
methods can not be utilized for STORING AC power
