Abstract

Menetelmä ja laitteisto kolmivaiheisen sähköverkon sähkölinjan häiriö- tai vikakohdan ennakoimiseksi ja/tai paikantamiseksi siten, että sähkölinjan varrelle viedään useita välimatkan päässä toisistaan olevia mittauspisteitä, joihin kuuluu jokaiselle vaihejohdolle tarkoitettu etätoteaja välimatkan päässä vaihejohdosta. Mittauspisteessä mitataan etätoteajien avulla erikseen jokaisen vaihejohdon jännitekentän voimakkuutta ja sähkölinjan vikakohta ennakoidaan ja/tai paikannetaan sähköjohdon jännitteen ja/tai jännitekentän voimakkuuden muutoksen avulla.
