Our proposal – Your beneFIT Trench France is manufacturing bushings & includes transformers bushings from 24kV up instruments transformers for more than 60 to 550kV, with rated current 800A to 5000A, years. generator bushings, current transformers & Previously known under the name of Haefely, voltage transformers. since 2004, the company belongs to the Siemens With more than 250 000 bushings in service Group. around the world, and a yearly production of As the global leader in Oil Impregnated 10 000 units, Trench is a leading player in the Paper technology (OIP), the products portfolio energy market. WHY SHOULD YOU BE CONCERNED ABOUT BUSHINGS? Transformer bushings are a critical component of a transformer and often the most forgotten one. The bushing allows the electrical power to flow from the source through the transformer and connect to the distribution network and finally to the end user. Transformer failures can result in unplanned outages which effect customers, reduce revenue and create a substantial cost to repair/rebuild the substation equipment. Several investigations of transformer failures have been done in the past, e.g. by CIGRE Transformer Reliability Survey reference WG A2.37 dated April 2012. According to these investigations bushing failures caused 17% of transformer failures. 2 THE PROVEN POWER. HOW DOES A BUSHING AGE ? The Oil Impregnated Paper (OIP) active part of the bushing, gaskets and O-rings are the key components of the bushings which will have the greatest impact on its lifetime. WHAT ARE THE FACTORS INFLUENCING THE BUSHING LIFETIME ? The high voltage OIP bushings have an average lifetime of 30 years depending on service conditions.

The step-by-step process of reaching the conclusion on the basis of dissolved gas analysis (DGA) as a key method of the investigations was presented. The considerations on the possible source of the analysis showed that the Duval triangle method, used in the analysis of the concentration of gases dissolved in oil samples taken from bushings, more reliably and unambiguously than the ratio method recommended in the IEC 60599 Standard, indicated a phenomenon which was identified in the insulation structure of bushings analyzed. Additionally, the results from DGA were found to be consistent with an internal inspection of bushings, which showed a visible trace of discharge on the inside part of the epoxy housing, as a result of the lightning induced breakdown.

  • Analysis of Partial Discharge in OIP Bushing Models
    Analysis of Partial Discharge in OIP Bushing Models ZEESHAN AHMED Degree project in Electical Engineering Electromagnetic Engineering Stockholm, Sweden 2011 XR-EE-ETK 2011:008 Analysis of Partial Discharge in OIP Bushing Models Zeeshan Ahmed Stockholm 2011 ________________________________________________________________ Electromagnetic Engineering School of Electrical Engineering Kungliga Tekniska Högskolan XR-EE-ETK 2011:008 Abstract A high voltage bushing is a very important accessory of power transformers. Bushings are used to insulate high voltage conductors where they feed through steel tank of a power transformer. There are different sources of electric stress that may result in degradation of bushing. Partial discharges (PDs) are one of the main sources of electrical degradation. PDs occur due to defects in electrical insulations, and can lead to insulation failure. This thesis is composed of two parts. The first part deals with design of a 145 kV oil impregnated paper (OIP) bushing by using capacitive radial grading technique. In capacitive grading the foils of calculated length are placed at predetermined radial distance between the paper layers in order to distribute voltage and electric field uniformly between high voltage conductor and ground potential. A 145kV OIP bushing was designed according to dimensions of ABB GOE type bushing. After calculations, the 145 kV bushing geometry was modeled in COMSOL Multiphysics in order to analyze the voltage and electric field distribution in the bushing. In the second part of this thesis a scaled down model was designed using the capacitive radial grading technique. After designing, the scale down model was implemented in COMSOL in order to ensure that the voltage and electric field distribution should be similar to the full scale model of bushing.
