Design and FEM Analysis of Trafoconnect

Transformer is an essential component used in electrical power distribution and transmission systems. Present electrical distribution system demands reliable, safe and efficient distribution of power. However, 8% of the transformer installed worldwide fails because of the improper connector systems. In this paper, we discuss novel design of transformer connector, called as trafo-connector, where LV cables are connected. The objective of the new design was to eliminate all the limitations of the conventional connector such as overheating due to improper contact, heavy weight, installation difficulties, etc. The newly developed Trafo-connector has significantly increased reliability of the transformer as it is light in weight, simple to install and maintains low contact resistance. Moreover, a detailed FEA analysis of short-circuit test and tensile load test are carried out as per IEC standard and are validated with experimental results.
