These are easily generated at a convenient voltage of 20 kV and are then transformed to a much higher voltage of various magnitudes. These voltage levels can either be 132 kV, 275 kV, 400 kV or 765 kV, which are then transmitted across the country. The voltage is transformed to a greater magnitude because a higher voltage will result in a lower current required for the same amount of power.

A delta connection is a connection where the ends of a three-phase winding are joined together. This means that the finishing end of one phase will be connected to the starting end of the other phase thus obtaining a closed circuit.\u00A0\u003C/p\u003E\n\u003Cp class=\u0022text-align-justify\u0022\u003EThe diagram below illustrates Star and Delta connections of a Transformer.\u003C/p\u003E\n\u003Cp\u003E\u003Ca href=\u0022mailto:hello@magnetgroup.co.za?subject=Electrical Enquiry\u0022\u003E\u003Cimg alt=\u0022Star delta\u0022 data-entity-type=\u0022file\u0022 data-entity-uuid=\u002214b211cb-aeca-4ddd-94f9-d0702f24cc22\u0022 src=\u0022/cms/drupal8-magnetgroup/sites/default/files/inline-images/Star%20delta.png\u0022 class=\u0022align-center\u0022 /\u003E\u003C/a\u003E\u003C/p\u003E\n\u003Cp\u003E\u00A0\u003C/p\u003E\n\u003Cp\u003EThe following are combinations in which a 3-phase transformer can be connected in:\u003C/p\u003E\n\u003Col\u003E\n\u003Cli\u003EY \u2013 Y (Star \u2013 Star)\u003C/li\u003E\n\u003Cli\u003EY \u2013 \u0394 (Star \u2013 Delta)\u003C/li\u003E\n\u003Cli\u003E\u0394 \u2013 Y (Delta \u2013 Star)\u003C/li\u003E\n\u003Cli\u003E\u0394 \u2013 \u0394 (Delta \u2013 Delta)\u003C/li\u003E\n\u003C/ol\u003E\n\u003Cp\u003E\u003Cstrong\u003EStar Connected Transformers\u003C/strong\u003E\u003C/p\u003E\n\u003Cp class=\u0022text-align-justify\u0022\u003EStar connected transformers, which are used in high-voltage operations, have the advantage of reducing the voltage on an individual transformer.
