In HT line Voltage is high & current is low

In LT Line Voltage is Low & current is high.

If we take a example of Stape down Transformer

Answer / virendra joshi

Universaly W(power) = V X I , mean for a constant power if
current increase Voltage decrese & if viltage increase
current Decrese. In LT voltage is less ( 415 ) so current
is high & fuse is bigger in size, simonteniously in HT volt
is more then current is less hence size of the fuse wire
will be lesse in terms of cross section.

Answer / al amaan

The size of the cable(Conductor) is choosed depends on the current value
For Example In 1000 KVA,11 KV/433 V Step down Transformer
Formula for calculate Power in KVA; P=√3*V*I
Current Formula; I=P/(V*√3)
Current in H.T side; ; I=1000/(11*√3)
I= 5.25 A
Current in L.T side; I=1000/(433*√3)
I= 133 A
From that the current in L.T side is higher than the H.T side So we use Higher dia cables in L.T side
