PCT No. PCT/DE95/00296 Sec. 371 Date Feb. 5, 1997 Sec. 102(e) Date Feb. 5, 1997 PCT Filed Feb. 22, 1995 PCT Pub. No. WO95/24725 PCT Pub. Date Sep. 14, 1995A device for monitoring the safety operation of power switches, in particular vacuum power switches in medium voltage switchboards. The device has a microprocessor unit that consists of a microprocessor, a microprocessor control and process-oriented storage means. The microprocessor is controlled by an angle pulse and a direction of a rotation recognition device. While the movement of the moving part of the power switch under the influence of states of operation is converted, the device detects the available data of the power switches. The device according to the present invention is especially well-suited in medium voltage switchboards for documenting and forecasting the real state of power switches.
