METHOD AND APPARATUS FOR LOCATING A FAULT ON A LINE |
摘要 |
<p>INVENTOR: OTTO LANZ INVENTION: METHOD AND APPARATUS FOR LOCATING A FAULT ON A LINE A method of, and apparatus for, locating a fault on a line, wherein current and voltage signals weighted relative to one another are formed from measurement signals corresponding to the line current and line voltage at a measurement location and after superimposing are used for a phase detection. At least one of the current signals or voltage signals is multiplied by a weighting factor at least approximately devoid of phase shift. From mutual relatively weighted current- and voltage signals there is determined the phase angle of a sinusoidal component of at least one auxiliary signal -- corresponding to the sum or difference of a respective pair of mutually relatively weighted measurement currents and measurement voltages --in relation to a reference phase position which can be correlated to a reference location at the line.</p> |
