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.
However, the energy in the relay or solenoid âopposes the original change in magnetic fluxâ, which is now trying to collapse. The coil can do this only by keeping the current flowing across the gap in the switch. The only way it can do this is by creating a Back EMF high enough to generate an arc across the gap.
