Automatically interrupt current during a fault (short circuit) to prevent equipment damage. visit report of 400kv power substation
A visit to a 400kV substation offers a firsthand look at the massive infrastructure required to stabilize and distribute bulk electricity across a regional grid. These high-voltage hubs serve as the critical link between power plants and local distribution networks. âš¡ Core Infrastructure & Components ) gas; more compact and housed indoors, ideal
