Power substations are part of the power grid, how electricity flows from the power plant to your house. Power substation=Umspannwerk. https://de.wikipedia.org/wiki/Umspannwerk A generator is a small machine that makes power for a building. If the power is out, hospitals have a generator so their life saving equipment inside continues to work. People have been stealing metals/materials from the power grid (Stromnetz) and from hospitals. As a result, hospitals have been having problems getting enough electricity to function. This is happening twice as much now as it happened last year.

copper and other valuable metals, which are better conductors

Ah! I work as an electrician in the film industry and this is a problem for us as well.... People steal copper because it is valuable. It can easily be melted down and recycled for cash.

A substation is where power 'steps down' in voltage/amps. In the U.S. our outlets are typically 120v 20AMPS. Power coming into a building might be significantly higher before it is distributed to each unit.

J. Maitland asks what is being done to crack down on the rise in thefts of metal, which is costing the UK up to £1,000,000,000 a year. Raids on power substations have doubled in the past 12 months and hospital generators have been targeted forcing, doctors to cancel operations. Thats all. It was from an english school book.
