Electrical Engineering & Electromechanics| Zusammenfassung: | Modern high-voltage systems of capacitive objects diagnostics through partial discharge characteristics are sophisticated complexes containing oil-filled equipment. For them, partial discharges (PD) with apparent amplitude of 1000 pC are considered quite admissible. A controlled conventional-configuration reactor with 110 kV-class insulation cannot be directly connected to a tested power cable with cross-linked insulation and rated PD level not exceeding 2 pC. Suppression of probable pulse noise is carried out by means of a high-voltage low-pass filter application. In the article, results of a high-voltage filter frequency characteristics calculation in the frequency range of the PD signal spectrum are presented. |
