Abstract (en)
[origin: EP3923684A1] The present invention provides a method for determining the location of an open-circuit fault in an electrical circuit that comprises a plurality of transformers (101), each transformer (101) having a primary winding (102) and a secondary winding (103), the primary windings (102) being electrically connected in series and each secondary winding (103) being electrically connected to a light-emitting diode (104). In the method, a constant-current regulator (105) is used to supply electric power to the primary windings (102), and the alternating voltage supplied by the constant-current regulator (105) is changed so that the light-emitting diodes (104) light up, the open-circuit fault being located between the transformers (101) that are electrically connected to the light-emitting diodes (104) having the smallest light intensities. The invention also relates to an electrical circuit.
