why connect alternator in star in generation

Alternators are connected primarily in star to achieve the following motives:br /Lesser stress on a rel='nofollow' href="https://www.dieselgeneratortech.com/generator-sets/How-to-Test-The-Insulation-Level-of-Diesel-Generator-Sets.html"insulation/a and Copper saving: Voltage per phase is less for a given line voltage which reduces insulation requirement and this also reduces the number of turns hence copper is also saved.br /Easy protection: Neutral grounding is necessary to allow zero sequence currents to flow to the ground in case of a fault.br /Elimination of harmonics: Star connection facilitates a neutral connection which is instrumental in eliminating triple harmonics.br /No circulating currents: In star connection we don't have circulating parasitic currents like in delta which lead to heating losses.
