Apparatus and Method of Detecting Faults in Medium Voltage Covered Conductors

Popis výsledku v původním jazyce

The electrical stray field is scanned in the surrounding of the covered conductor, after which the impulse components, which are purposely digitalized and further frequency filtered, are separated from the obtained signals, which takes place by eliminating to 20 kHz high frequency signals. After the frequency filtration process the effective values of the impulse components, which correspond to a defined and pre-set time period and selected length of time intervals, are computed. The values are registered and the effective values which correspond to diverse time scanning periods are subsequently and/or simultaneously compared. Faults in the medium voltage covered conductors are detected by comparing the common values. The apparatus includes an electrical stray field sensor which is connected through the impulse component detection unit to the frequency filter, which is further connected to the to the computing unit whose output is linked to the evaluation unit. The impulse component de
