Belt conveyor behaviour at run-up, especially when fully loaded, is one of the most important factors which influence their failure rate in open pit mines. The paper describes a practical use of a power network complex analyser for measurement of electric drives of drive stations of long distance belt transport at belt conveyor run-up and operation. The measurement of an older belt convey-or without a frequency transducer and of an upgraded conveyor with frequency controlled drives is described. The measurement of electric quantities of the drives is completed with rotation measurement in order to obtain a torque value from the active power.
