Identify the properties for neutral wire and earth wire from the given list.
(i)
It is connected to the neutral point of the transformer that is earthed at the
substation.
(ii) It is a solid earth at the substations.
(iii) Unbalanced current flows through it.
(iv) Only fault current flows through it.
Neutral
wire: (i) and (iv); Earth wire: (ii) and (iii)
Neutral
wire: (i); Earth wire: (ii), (iii) and (iv)
Neutral
wire: (i), (iii) and (iv); Earth wire: (ii)
Neutral
wire: (i) and (iii); Earth wire: (ii) and (iv)
Neutral
wire: (i) and (iii); Earth wire: (ii) and (iv)
Neutral
wire : It is connected to the neutral point of the transformer and is earthed
at the sub-station through which unbalanced current flows. Earth wire: This is
the solid earth on the wire substation through which only the fault current
flows.
Hence,
the correct option is (D).
