A Methodology for the Assessment of Hvdc-xlpe Cable Insulation
The purpose of this work is to present and to discuss a methodology for the assessment of materials intended to HVDC-XLPE cables, particularly as regards the evaluation of the effects of material formulation on space charge accumulation within the insulation. Sample design, testing method and protocol and criteria used for the material evaluation are specifically considered. It will be shown th...
متن کاملOn-line Partial Discharge Monitor System of XLPE Power Cable Based on Virtual Instrument
High voltage XLPE power cable is a very important part of power system. The degree of electric-tree aging in the cable can be estimated effectually by measuring partial discharge. An on-line partial discharge monitor system of XLPE power cable was developed based on the virtual instrument designing conception. This system has the advantage of wide analog bandwidth, excellent anti-interference a...
متن کاملResearch on Partial Discharge Localization in XLPE Cable Accessories Using Multi-Sensor Joint Detection Technology
A multi-sensor joint detection technology was proposed based on the theory of the high frequency current transformer (HFCT) method, Ultra-high frequency (UHF) method and acoustic emission (AE) method. An experimental partial discharge (PD) testing was applied on XLPE cable with artificial defect signals. The experimental results show that the multi-sensor joint detection technology will help to...
متن کاملEstimation of HVDC Partial Discharge Incident Occurrences
Similar to AC system, the insulation system of DC system also gets affected. The HVDC station is a challenging environment for measurement of partial discharge level due to very high interference levels caused from the switching of thyristor-controlled converters. There is also significant interference from external air-corona due to high electric stress at the surface of conductors and hardwar...
متن کاملField distortion by a single cavity in HVDC XLPE cable under steady state
Electric field distribution in high voltage direct current (HVDC) cross-linked polyethylene (XLPE) cable at steady state is researched in this study. Under the condition that no cavity exists, equations describing the critical temperature difference for field reversal, and electric field distribution at steady state are proposed. When the cable with cavity is studied via the finite element anal...
