Simultaneous handling of two 40 MVA transformers enabled the project supplier to leverage synergy \u2014 shared logistics solutions, shared foundation preparation, and parallel commissioning. The n-1 redundancy requirement means each transformer must independently be able to cover the entire substation's normal load.<\/p>\n<p>Large-scale crane solutions were used during installation to position the transformers precisely on their designated foundation positions. Primary and secondary connections were made carefully in phases so that each unit's switching to production mode could be independently verified.
