Abstract

In three-phase applications, the direction of rotation can be determined from signal flows in the phase conductors, usually on the basis of indicator diagrams. According to the invention, the individual phases are traced at given time periods and the measuring values or the interpolated approximation values or just the signs of the values are evaluated by means of an evaluation algorithm in order to determine the direction of rotation at at least two points in time. In addition to the basic method, preferably half-wave rectified signal flows from individual phase conductors are evaluated according to an ideal sinusoidal flow. The inventive method can be advantageously used in conjunction with a digital overload relay to determine the direction of rotation, whereby an available digital signal control device and/or signal processing device is used.
