Abstract
A method and arrangement are provided for controlling electric current in a tether cable of an electrically driven mining vehicle. An indicator of an equivalent cycle current that flows through said tether cable is determined, and one or more descriptors of an actual state of dynamically changing conditions of the tether cable are obtained. A current limiting value is determined on the basis of the indicator and the descriptors, and a total amount of current is limited that the mining vehicle draws through the tether cable to a value smaller than or equal to the determined current limiting value.
