WO2005022175 A UPAB: 20050504 NOVELTY - The device has an electrical energy source (100) and an electrical load (108) coupled to opposite ends of the electrical line (104,106), with a measuring device (120), using high frequency measuring pulses for measuring faults along the electrical line via a pulse reflectrometry method and a unit (160) for decoupling of the measuring pulses from the energy source and the load. The electrical output of the electrical energy source has a lower frequency than the measuring pulses, or is provided by a DC signal, the decoupling unit using magnetic sleeve components, magnetically coupled with decoupling sections (150,152,154,156) between the source and the line and between the line and the load, by enclosing the respective line sections. DETAILED DESCRIPTION - An INDEPENDENT CLAIM for a method for monitoring an electrical line is also included. USE - The device is used for monitoring an electrical line used for transmission of power between a source and a load in a current circuit. ADVANTAGE - Device provides line monitoring without interrupting transmission of power between electrical energy source and load.
