Abstract (en)
[origin: EP2750155A1] The apparatus has a main current circuit, and an auxiliary circuit in which current passes when the main circuit is cut-off after occurrence of a short-circuit. The auxiliary circuit comprises a current limiting resistor including flat coils (5) maintained by side flanges (1, 3) made of thermoplastic material. The resistor includes a variation unit for varying ohmic value of the resistor by association of the coils in parallel. Each coil includes a wire equipped with an electric insulation unit, where the wire is made of stainless steel. Independent claims are also included for the following: (1) a method for winding a magnetically neutral coil (2) a method for forming electric connections of a resistor.
