Abstract [sv]

Nowadays the measurement of earth conduction in interlocking plants with voltages of 100 kV and more is made by the “starkströmsmetoden”. To be able to do measurements with this method pilot wires with kilometers of length are often required. The solution to this problem is disposition of telecommunication-wires. By the time fiber conductors increasingly are introduced there is a cumulative problem to find galvanic conductors with the required length to be able to do these earth conduction measurements. With motive by this an interest has awoken to find a new method. The work has been concentrated on finding a new method where these pilot wires won’t be needed. A method with direct current has been evaluated and tested in field. “Likströmsmetoden” is based on using the part of the power line that is not connected as a voltage measurement power line and thus be able not to use these telecommunication wires.
