Abstract

Dağıtım sistemlerinde kullanılan yüksek gerilim yer altı kabloları estetik, güvenilirlik, düşük bakım maliyetleri ve çevresel faktörlere dayanıklılık gibi avantajlar sağlar. Ancak bunların ilk kurulum maliyetleri, havai hatlara göre oldukça yüksektir ve arıza tespiti zordur. Bu nedenle dielektrik parametrelerinin derinlemesine analizi oldukça önemlidir. Yüksek gerilim yeraltı kablolarının üretici firma tarafından verilen elektriksel değerleri genellikle nominal işletme şartları için kullanılmaktadır. Ancak değişken işletme şartları, kablo yalıtımının dielektrik dielektrik parametrelerini de değiştirmekte olup yalıtımın daha hızlı yaşlanmasına ve beklenmeyen arızalara neden olmaktadır. Ancak değişken işletme şartlarında, kablo yalıtımının dielektrik parametreleri de değişmekte olup, sistemin çalışmasında aksamalara ve beklenmeyen arızalara neden olabilmektedir. Bu nedenle, kablo yalıtımının dielektrik parametrelerinin farklı işletme koşulları altında belirlenmesi ve bu işletme koşullarının yalıtım üzerindeki etkilerinin ortaya konması önem arz etmektedir. Bu çalışmada, 12/20 kV nominal gerilimli, XLPE izoleli bir yüksek gerilim yeraltı kablosunun, farklı işletme koşullarındaki (gerilim, sıcaklık ve frekans) dielektrik parametreleri (kapasite, bağıl dielektrik katsayısı, dielektrik kayıp, tanδ) deneysel olarak belirlenmiştir. Elde edilen sonuçlara göre, nominal çalışma sınırları içerisinde dahi kablo yalıtımının dielektrik özelliklerinin farklı gerilim, frekans ve sıcaklık ile önemli ölçüde değiştiği gözlemlenmiştir.

An EXPERIMENTAL STUDY ON DIELECTRIC PARAMETERS OF XLPE INSULATED HIGH VOLTAGE CABLES UNDER DIFFERENT OPERATING CONDITIONS

Abstract

High voltage underground cables used in distribution systems provide benefits including aesthetics, reliability, low maintenance costs, and resistance to environmental factors. However, their initial installation expenses are considerably higher than overhead lines, and fault detection is quite challenging. Thus, a deep analysis of dielectric parameters is crucial. Typically, electrical specifications of high voltage underground cables provided by the manufacturer are used for nominal operating conditions. However, it is essential to acknowledge that variations in operational conditions have a discernible impact on the dielectric characteristics of cable insulation. This phenomenon results in an accelerated aging process of the insulation material and contributes to unexpected failures. Hence, it is imperative to determine dielectric parameters of cable insulation under varying operational conditions and elucidate the impact of these operational states on insulation properties. This study involved experimental determination of the dielectric parameters, including capacitance, relative dielectric constant, dielectric loss, and tanδ, for a XLPE insulated high voltage underground cable, designed for a nominal voltage of 12/20 kV. These assessments were performed under varying operating conditions, specifically for distinct voltage, temperature, and frequency. Based on the acquired findings, it is evident that the dielectric characteristics of the cable insulation exhibit substantial variations in response to alterations in voltage, temperature, and frequency, even when operating within the defined nominal limits.
