Method for determining failure location of line for determining line interruption in e.g. aircraft, involves determining position of error on line from ratio of voltage reference effective value and voltage effective value of line

摘要

The method involves applying a changed voltage signal i.e. sinusoidal voltage signal, to a line (10.2) with an error. A voltage effective value is determined with respect to a reference potential from a measuring line (10.3), where frequency of the sinusoidal voltage signal lies at a range of 100 Hertz to 10 kilo Hertz. A position (12) of the error on the line is determined from a ratio of a voltage reference effective value and a voltage effective value of the line afflicted with the error based on entire length of the line afflicted with the error. An independent claim is also included for a device for performing a method for determining a failure location of a line.
