Abstract: 2.1  By measuring methods in which a test current is applied to the protective conductor, dangerous contact voltages can occur in the case of faulty power systems. The danger associated with this is to be eliminated by the invention. 2.2  Into the measuring sequence for determining various measuring quantities, test measurements are inserted with the aid of which the contact voltage (UA) occurring in each case is measured at short intervals. If this voltage exceeds a predetermined limit value (UBL) which corresponds to the limit value of the permissible contact voltage (UB), the test current (IK) is switched off and thus the measuring sequence is interrupted. 2.3  The invention is applied in measuring and test instruments which are equipped with a computer. <IMAGE>

Abstract: In a system for transmitting an electrical power supply by means of an over-head power transmission line supported by power transmission towers, a fault such as a short-circuit fault and a ground fault is detected by providing optical current sensors (1) having opto-magnetic elements (3) and opto-electric field elements (20) on respective con­ductors (7) of the transmission line to detect a fault current and fault voltage on the basis of the Faraday's effect and Pockel's effect. Light beams passing through the elements are modulated by the magnetic fields induced by the currents passing through the conductors and the voltages on the conductors, and thus include information about the current and voltage. There is further provided a circuit for calculating a distance to a fault point in accordance with the detected current, voltage and a phase difference therebetween and a known impedance of the power transmission line. The thus calculated distance to the fault point is displayed on a display device which is arranged at the power transmission tower or the sub-­station.
