Abstract

Electrical Insulation in Sub-Atmospheric Pressures under High Frequency Applied Fields.
Hulya Kirkici, PhD., Fellow-IEEE
Professor and Chair, Electrical and Computer Engineering
University of South Alabama, Mobile Alabama, USA

Power devices and systems operating in vacuum or sub-atmospheric pressures are more susceptible to partial discharges, corona, volume discharges, or fully developed breakdown due to the partial vacuum conditions. In space/aerospace vehicles, these activities are great concerns and require major design considerations.  Furthermore, space/aerospace power systems operate at voltages higher using switch-mode conversion. In return, higher switching frequencies impose higher stress on dielectrics, than the dc fields, in space/aerospace power systems.  This presentation is an overview of dielectric material fundamentals, including the high voltage electrical insulation of space/aerospace power and high voltage pulsed systems over the years. Also an overview dielectric breakdown of gases and solids under non-uniform, high frequency and high fields applied fields and operated in sub-atmospheric pressures.

Abstract

Increase of Operation Reliability of HV Apparatus through PD Monitoring
Wojciech Koltunowicz, PhD, D.Sc.
Senior Technical Consultant
OMICRON Energy Solutions GmbH, Berlin, Germany

Partial Discharge (PD) monitoring is nowadays a recognized technique for the condition based assessment of the insulation of high voltage (HV) apparatus. Since its massive introduction in the late eighties, different solutions for sensors and acquisition techniques have been proposed, applied and lately acknowledged by international standards. In this presentation, the challenges in continuous PD monitoring of HV power cables, transformers, gas insulated substation and rotating machines will be discussed. In the case of power cables, the presentation deals with continuous monitoring of 420 kV XLPE cable lines applied for buried cables and cables in the underground tunnels. In the case of transformers, the maintenance and operation recommendations based on the results obtained from continuous monitoring on two identical old transmission transformers will be presented. PDs are measured at the bushing measuring taps and in the ultra-high frequency (UHF) range with an antenna installed within the transformer tank. In the case of rotating machines, an automated PD defect classification system, which identifies the type of stator winding insulation defect and its location, implemented in the continuous monitoring system will be described. The last part of the presentation will be dedicated to GIS PD diagnostics, and in particular to the CIGRE recommendations related to the sensitivity check of UHF PD monitoring system. The case studies described in this presentation show that incipient insulation defects can be detected early and their evolution can be monitored supporting the asset managers to derive prompt actions.

Abstract

A Journey on FRA for fault detection in Power Transformers Offline to Online – Challenges and Opportunities
Syed Islam, PhD, FIET, FIEAust, SMIEEE, CPEng.
John Curtin Distinguished Professor of Electrical Power Engineering
Curtin University, Perth
Australia

Frequency Response Analysis (FRA) is now an well established and widely accepted technique to monitor the mechanical integrity of a power transformer condition. FRA has matured as a technique over the past two decades to the point that there are now commercially available equipment for testing. While the equipment and the test results have been established as credible tool to assess the mechanical integrity of a transformer such as axail and radial bucklings of winding, tap changer faults, and loss of clamping pressure. However, the technique largely have focussed on offline measurements and the industry is really looking forward to an online tool. There are now considerable effort exerted in developing an online tool. This keynote talk will focus on the recent progresses in online FRA tool and its associated challenges as well as provide a background to the technique and historical progress.

Abstract

Some common errors in experimentally-based scientific papers
Dr Robert Fleming
Former Editor-in-Chief of the IEEE Electrical Insulation Magazine

The mechanics of writing a scientific paper for publication in a stringently-refereed journal vary greatly from author to author, mainly because there are no hard-and-fast structural requirements, apart from a few broad headings, e.g., in the case of an experimentally-based paper, Introduction, Experimental, Results, Discussion, Conclusions. Consequently in this talk I will not specify how to go about writing a scientific paper, but, drawing on ten years experience as Co-Editor-in-Chief of the IEEE Electrical Insulation Magazine (and now retired), I will point out a few common errors which must be avoided. An example is describing in detail in the text the variation of some measured quantity with one or more parameters, already presented in a Figure, rather than concentrating on the important features.
