| 摘要 |
The present invention is directed to locating electrical faults (61) in an electrical circuit (50), in particular electrical faults (61) in transmission wires (60) of an electrical circuit (50). Examples of the present invention provide a method and apparatus for opening a switch (90) in the electrical circuit (50 9 to cause an open circuit or discontinuity at the fault (61); transmitting (100) a signal to be reflected from the open circuit or discontinuity and receiving (100) the signal reflected from the open circuit or discontinuity to determine the location of the fault. Examples of our invention are particularly suitable for high voltage systems, for example over 100V. |
