Remote detector of electric field of a 3kV DC traction line: a preliminary study

Summary - The paper tackles the problem of ascertain- ing the 3kVDC voltage disconnection of traction lines by means of a device capable of detecting the electrostatic field of an overhead cable, as a part of a safety campaign pro- moted by the Italian railway network RFI SpA within the entire network.
The main methods of field detection are reviewed, some of which are commonly used, others are still under study. For each considered device we highlight advantages and limits, obtaining criteria in view of the design and implementation of a new aid for RFI personnel, responsible of the traction line maintenances.
