In a 3-wire DC transmission system, if
the potential difference is 460 V, then the potential difference of positive
outer above the neutral will be :
-115 V
230 V
115 V
460 V
230 V
In a 3-wire DC transmission system, if
the potential difference is 460 V, then the potential difference of positive
outer above the neutral will be 230 V.
Hence, the correct option is (B).
