Badania odbiorcze i diagnostyczne nowo zainstalowanych oraz już eksploatowanych przesyłowych kabli elektroenergetycznych stają się coraz ważniejszą kwestią w zakresie zapewniania wysokiej jakości obwodów kablowych. W ciągu ostatnich 20 lat, oprócz tradycyjnych testów wykonywanych przy użyciu ciągłego napięcia przemiennego oraz systemów rezonansowych AC, metoda wykorzystująca tłumione napięcie przemienne (DAC) stała się alternatywnym sposobem testowania stosowanym w wielu krajach. Próby napięciowe z monitorowaniem wyładowań niezupełnych (PD) przy użyciu tłumionego napięcia przemiennego dają podobne wyniki w zakresie występowania wyładowań niezupełnych oraz ich lokalizowania w porównaniu z tradycyjną metodą rezonansową. Próby napięciowe z monitorowaniem wyładowań niezupełnych (PD) przy użyciu DAC z powodzeniem stosuje się w kontroli jakości nowo zainstalowanych zarówno lądowych, jak i morskich połączeń kablowych (do 230 kV) wysokiego napięcia (WN) o dużych długościach. Testy te stanowią solidną podstawę do wykonywania czynności związanych z zapewnianiem jakości oraz konserwacją obwodów kablowych w okresie eksploatacji na podstawie aktualnego stanu instalacji.

Testing of the newly installed and service aged transmission power cables is becoming more and more important issue to ensure high quality of the cable circuits. During the past 20 years, in addition to the traditional continuous AC voltage testing using AC resonant systems, the damped AC method has become an alternative testing way accepted in many countries. PD monitored voltage withstand testing using damped AC voltages provides similar results for PD occurrence and the localization to the traditional resonant method. PD monitored damped AC voltage testing was successfully applied for quality control of newly installed on – and offshore long length HV cable connections up to 230 kV. Such tests form a sound basis for quality assurance and condition-based maintenance during the cable’s service life.
