Estimation 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 کاملReturn to Session PARTIAL DISCHARGE DETECTION IN POWER CABLES: PRACTICAL LIMITS AS A FUNCTION OF CABLE LENGTH
Power cables behave as transmission lines as regards partial discharge (PD) pulse propagation. Attenuation and dispersion phenomena have, therefore, great influence on the detectability of PD pulses, particularly when long cable routes and detection from terminals are considered. This paper presents an approximate model to infer PD pulse waveform as a function of the distance travelled along th...
متن کاملThe Application of Partial Discharge Detection for the condition assessment of XLPE Power Cables
Partial discharge (PD) detection is an important means in the condition-based maintenance of high voltage apparatus including crosslinked polyethylene (XLPE) power cables. In this contribution, we introduce the recent work in Shanghai municipal electric power company on the condition-based maintenance of XLPE power cables. As to how to carry out the PD detection in different circumstances, thre...
متن کاملAdvanced technique for partial discharge detection and analysis in power cables
Polymeric cables are the most common choice for transmission and distribution in populated areas, as well as for the connection of components (transformers, GIS, etc.) in new power stations, replacing paper-oil cables. Indeed, they do possess superior characteristics with respect to oil-filled cables. As an example, they do require lower maintenance, they are lighter (easier to deploy) and, in ...
متن کاملPractical Aspects for Design of Indirect Measurement in Dynamic Systems
In different areas of science and engineering are used different indirect measurement procedures that lead to obtaining the quantity desired. In this paper is described the considerations about indirect measurement system (IMS). Is realized the analysis between direct measurement and indirect measurement, presenting the limitations of the estimator. The IMS are classified under the methodologic...
