Abstract
A mining vehicle includes electric components, devices or machines operating at alternating voltage and having a specific nominal voltage. Power is fed to the mining vehicle from an alternating current network with a specific voltage level. The mining vehicle further includes a transformer arranged to transform the voltage level of the alternating current network into the nominal voltage. When a voltage higher than the nominal voltage is fed to the transformer, the transformer lowers this higher voltage to the nominal voltage. When a voltage lower than the nominal voltage is fed to the transformer, the transformer raises the voltage to the nominal voltage. The transformer is arranged to feed the electric component, device or machine both when a voltage lower than the nominal voltage is fed to the transformer and when a voltage higher than the nominal voltage is fed to the transformer.
