As we reported last year, company founder Christian von Koenigsegg was convinced that the 1341-hp hybrid megacar would be able to slice a âvery significant chunkâ from the 918âs lap time, although he also admitted that he hated the need to have to prove the potency of his companyâs products with a Nordschleife record.
One of the basic functions of switchgear is protection, which is interruption of short-circuit and overload fault currents while maintaining service to unaffected circuits. Switchgear also provides isolation of circuits from power supplies.
How relays work. Here are two simple animations illustrating how relays use one circuit to switch on a second circuit. When power flows through the first circuit (1), it activates the electromagnet (brown), generating a magnetic field (blue) that attracts a contact (red) and activates the second circuit (2).ther relays are normally closed (NC; the contacts are connected so a current flows through them by default) and switch off only when the magnet is activated, pulling or pushing the contacts apart. Normally open relays are the most common. Here's another animation showing how a relay links two circuits together.
