DIAGNOSTICS OF OIL-FILLED EQUIPMENT BY MEANS OF REGISTRATION OF PARTIAL DISCHARGES

open access: yesСовременная наука и инновации, 2023
One of the main tasks of diagnostics of oil-filled equipment is to measure the characteristics of partial discharges in isolation. In the subsequent planning of repairs, assessment of the degree of danger and maintainability of the defect, it becomes ...

Partial discharges characteristics study in XLPE cable insulation with multiple defects [PDF]

open access: yesОмский научный вестник, 2021
The paper simulates the electric field intensity picture in the cable with one and several defects. Modeling has shown that the presence of several closely spaced defects does not lead to an increase in the electric field intensity in comparison with

Study on the Effect of Void Geometry and Location on Electric Field Distribution and Partial Discharges in HVDC Cables [PDF]

open access: yesE3S Web of Conferences, 2023
Nowadays HVDC transmission systems are preferred over HVAC systems because of their less power loss and high reliability. In the HVDC cable transmission system, there is a problem of Partial Discharges (PD) occurring due to cavities of the dielectrics in

Method of fault‐type recognition based on the dissolved gas analysis using a set of diagnostic criteria

open access: yesIET Generation, Transmission & Distribution, 2023
This paper proposes a method for recognising the fault type using a set of diagnostic criteria. Existing approaches to the interpretation of dissolved gas analysis (DGA) results usually rely on single diagnostic criteria.
