Question

Accepted Answer

A substation is an electrical system that transforms voltage from high to low or vice versa for transmission and distribution.

Equipments required for a substation include transformers, circuit breakers, isolators, lightning arresters, and control panels.
Conductor is a material that carries electrical current. It is graded based on its resistance to heat and current carrying capacity.
Cables are insulated conductors used for transmitting electrical power. HT cables have higher voltage ratings than LT cables.
HT cables are usually identified by their red or yellow color, while LT cables are identified by their blue or black color.
