What is the difference between station and substation?

The main difference we find between a transformer station and an electrical substation is the magnitude of the installations. While transformer stations are linked to high/medium-voltage transmission systems, electrical substations are designed to support and transform lower voltages.

Why do substations have gravel?

The resistivity of gravel is about 5000 Ohm-m and thus, when gravel is filled in outdoor Switchyards & Substations, it increases the tolerable touch & step potentials of humans accessing the outdoor Switchyards & Substations, thereby reducing the risk of electric shock.

Do substations have transformers?

The transformer is the heart of the substation. The transformer changes the relationship between the incoming voltage and current and the outgoing voltage and current. Substation transformers are rated by their primary and secondary voltage relationship and their power carrying capability.
