### sense in the lessons

In science and safety lessons about electricity, power stations make electricity, pylons carry it, and substations change the voltage before it reaches homes. Safety: never climb into a substation or fetch a ball from one — the electricity can kill; tell an adult or call the power company. Signs say «Danger of death».

### examples

- A substation turns very high voltage into safer voltage for homes. [tree →](https://md.mova.elamur.ai/free/en/corpora/dictionaries/school/S/substation/#x1)
- Never go inside a substation fence. [tree →](https://md.mova.elamur.ai/free/en/corpora/dictionaries/school/S/substation/#x2)
- Our ball went over the fence into the substation, so we called an adult. [tree →](https://md.mova.elamur.ai/free/en/corpora/dictionaries/school/S/substation/#x3)
- The lights went out when the substation was hit by lightning. [tree →](https://md.mova.elamur.ai/free/en/corpora/dictionaries/school/S/substation/#x4)

### note

Countable noun: sub- (under, smaller) + station. Electricity at a substation is extremely dangerous even without touching: stay away. In science, voltage is stepped up for long-distance cables and stepped down at substations.

### In the corpora
