Parcijalna pražnjenja i IEC standardi 60840 i 62067: Simulacijska podrška za poticanje promjena ISSN 1330-3651 (Print), ISSN 1848-6339 (Online) DOI: 10.17559/TV-20141118124625 PARTIAL DISCHARGES AND IEC STANDARDS 60840 AND 62067: SIMULATION SUPPORT TO ENCOURAGE CHANGES Mirza Batalović, Kemo Sokolija, Mesud Hadžialić, Nejra Batalović Preliminary notes This paper addresses some shortcomings of existing IEC standards related to analyses of cable systems with polymer insulation (IEC 60840 and IEC 62067). The focus is on partial discharges measurement, completely neglected in present version of these standards, and justification of the needs for their inclusion in the standards through appropriate procedures. If included in the standards the procedures would provide an effective way to identify and detect the defects that might appear during the cable system installation and to forestall their appearance during exploitation. The simulation evidences, to suggest and justify the changes in the standards, through a modelling of partial discharge phenomena using contemporary software tool (COMSOL) are provided in this paper. Keywords: COMSOL model; IEC standards; partial discharges Parcijalna pražnjenja i IEC standardi 60840 i 62067: Simulacijska podrška za poticanje promjena Prethodno priopćenje Ovaj rad upućuje na izvjesne nedostatke postojećih IEC standarda koji se odnose na analizu kabelskih sistema s polimernom izolacijom (IEC 60840 i IEC 62067). Fokus je na mjerenju parcijalnih pražnjenja, potpuno zanemarenih u aktualnoj verziji ovih standarda,te opravdanosti potreba za njihovo uključenje u standarde kroz odgovarajuće procedure. Ukoliko bi se uključile u standarde, procedure bi osigurale učinkovit alat za identifikaciju i detekciju defekata koji se mogu pojaviti za vrijeme instalacije kabelskih sistema i spriječiti njihovu pojavu tijekom eksploatacije.

  • Liquid Dielectrics, Their Classification, Properties, and Breakdown Strength
    CHAPTER 6 LIQUID DIELECTRICS, THEIR CLASSIFICATION, PROPERTIES, AND BREAKDOWN STRENGTH From the point of view of molecular arrangement, a liquid can be described as “ highly compressed gas ” in which the molecules are very closely arranged. This is known as kinetic model of the liquid structure. A liquid is characterized by free movement of the constituent molecules among themselves but without the tendency to separate. However, the movement of charged particles, their microscopic streams, and interface conditions with other materials cause a distortion in the otherwise undisturbed molecular structure of the liquids. The well known terminology describ- ing the breakdown mechanisms in gaseous dielectrics — such as impact ionization, mean free path, electron drift, and so on — are, therefore, also applicable for liquid dielectrics. Liquid dielectrics are accordingly classifi ed in between the two states of matter; that is, gaseous and solid insulating materials. Wide range of application of liquid dielectircs in power apparatus also characterizes this intermediate position of liquid dielectrics. Insulating oils are used in power and instrument transformers, power cables, circuit breakers, power capacitors, and so on. Liquid dielectrics perform a number of functions simultaneously, namely: • insulation between the parts carrying voltage and the grounded container, as in transformers • impregnation of insulation provided in thin layers of paper or other materials, as in transformers, cables and capacitors, where oils or impregnating com- pounds are used • cooling action by convection in transformers and oil fi lled cables through circulation • fi lling up of the voids to form an electrically stronger integral part of a com- posite dielectric • arc extinction in circuit breakers High Voltage and Electrical Insulation Engineering, First Edition.

  • Understanding Electrical Treeing Phenomena in Xlpe Cable Insulation Adopting Uhf Technique
    Journal of ELECTRICAL ENGINEERING, VOL. 62, NO. 2, 2011, 73–79 UNDERSTANDING ELECTRICAL TREEING PHENOMENA IN XLPE CABLE INSULATION ADOPTING UHF TECHNIQUE ∗ ∗ ∗∗ Ramanujam Sarathi — Arya Nandini — Michael G. Danikas A major cause for failure of underground cables is due to formation of electrical trees in the cable insulation. A variety of tree structure can form from a defect site in cable insulation viz bush-type trees, tree-like trees, fibrillar type trees, intrinsic type, depending on the applied voltage. Weibull studies indicate that a higher applied voltage enhances the rate of tree propagation thereby reducing the life of cable insulation. Measurements of injected current during tree propagation indicates that the rise time and fall time of the signal is of few nano seconds. In the present study, an attempt has been made to identify the partial discharges caused due to inception and propagation of electrical trees adopting UHF technique. It is realized that UHF signal generated during tree growth have signal bandwidth in the range of 0.5–2.0 GHz. The formation of streamer type discharge and Townsend type discharges during tree inception and propagation alters the shape of the tree formed. The UHF signal generated due to partial discharges formed during tree growth were analyzed adopting Ternary plot, which can allow one to classify the shape of tree structure formed. K e y w o r d s: power cables, cable insulation, partial discharge, UHF signal, electrical breakdown, failure analysis, XLPE, ternary plot 1 INTRODUCTION The conventional method of identifying the discharges is through identification of luminous discharges from the In recent times, cross linked polyethylene (XLPE) ma- defect site due to tree propagation, acoustic signal radi- terial is used as insulation material in high voltage AC ated during tree propagation and by measuring the par- and DC cables.

  • Preparation of Monodisperse Microbubbles in a Capillary Embedded T-Junction Device and the Influence of Process Control Parameters on Bubble Size and Stability
    Preparation of monodisperse microbubbles in a capillary embedded T-Junction device and the influence of process control parameters on bubble size and stability A thesis submitted in partial fulfilment of the requirements for the degree of Doctor of Philosophy By Maryam Parhizkar Department of Mechanical Engineering University College London Torrington Place, London WC1E 7JE U.K March, 2014 Declaration I, Maryam Parhizkar, confirm that the work presented in this thesis is my own. Where information has been derived from other sources, I confirm that this has been indicated in the thesis. ………………………………….. Maryam Parhizkar 1 Abstract The main goal for this work was to produce microbubbles for a wide range of applications with sizes ranging between 10 to 300 µm in a capillary embedded T- junction device. Initially the bubble formation process was characterized and the factors that affected the bubble size; in particular the parameters that reduce it were determined. In this work, a polydimethylsiloxane (PDMS) block (100 x 100 x 10 mm3) was used, in which the T-shaped junction was created by embedded capillaries of fixed outer diameter. The effect of the inner diameter was investigated by varying all the inlet and outlet capillaries’ inner diameter at different stages. In addition, the effect of changes in the continuous phase viscosity and flow rate (Ql) as well as the gas pressure (Pg) on the resulting bubble size was studied. Aqueous glycerol solutions were chosen for the liquid phase, as they are widely used in experimental studies of flow phenomena and provide a simple method of varying properties through dilution.
