Why do distribution substations often have a neat appearance?

Answer & step-by-step solution
Correct answer: D. Because underground cables are used for input and output connections
Quick explanation

D — Underground cables are used for incoming and outgoing connections, so there are no exposed overhead conductors around the substation.

Detailed solution (in the paper’s original language)

સમજૂતી

ઘણા distribution substations માં incoming અને outgoing connections માટે exposed overhead conductors ના બદલે underground cables વપરાય છે.

Visible overhead conductors અને સંબંધિત structures ઓછા હોવાથી installation નો external appearance વધુ clean અને attractive દેખાય છે, ખાસ કરીને urban areas માં.

મુખ્ય ખ્યાલ

Underground incoming/outgoing cables visible overhead clutter ઘટાડે છે.

પરીક્ષા મુદ્દો

આવા layout પ્રશ્નોમાં practical installation viewpoint રાખો.

ઝડપી ટ્રિક

Underground cables → cleaner substation appearance.

બીજા વિકલ્પો ખોટા કેમ છે

Painting, remote location અથવા compact equipment આ PYQ માં પૂછાયેલ મુખ્ય કારણ નથી.

સામાન્ય ભૂલ

Paint colour જેવી visually plausible પરંતુ electrically unrelated બાબત પસંદ કરવી.
