Failure in power transformer can be catastrophic to electric systems, since transformers play a vital role in the power sector. Metallic particles in transformer oil lead to Partial discharge which can result in serious conditions. | Finite element analysis of power transformer International Journal of Mechanical Engineering and Technology IJMET Volume 10 Issue 03 March 2019 pp. 1384 1391 Article ID IJMET_10_03_139 Available online at http ijmet JType IJMET amp VType 10 amp IType 3 ISSN Print 0976-6340 and ISSN Online 0976-6359 IAEME Publication Scopus Indexed FINITE ELEMENT ANALYSIS OF POWER TRANSFORMER Dr. N. Vasantha Gowri and Zainab Akthar Chaitanya Bharathi Institute of Technology Hyderabad India ABSTRACT Failure in power transformer can be catastrophic to electric systems since transformers play a vital role in the power sector. Metallic particles in transformer oil lead to Partial discharge which can result in serious conditions. The existence of conducting particle in the winding of a transformer accumulates electrical stress. Simulations are carried out for the electrical analysis of power transformer. The impact of this electrical stress on particle at different position has been analyzed in this paper. Key words Partial Discharge Power Transformer finite element method. Cite this Article Dr. N.

INTRODUCTION Power Transformer being a vital element in the electrical network is anatomized such as to protect it from any catastrophic failure. The transformer collapse can be perilous. To avoid transformer from being damaged its testing and analysis is necessity. Studies divulge that over 85 of failure in HV equipment is due to Partial Discharge PD .The integrity of insulation HV equipment is needed to be confirmed with PD analysis in each stage of manufacturing commissioning for the reliability of HV winding of transformer. Analysis of PD is performed for quality assessment of the insulation. The PD analysis detects the .
