At Albert Einstein Faculty construction, the operation required a 13.8 kV test with generators installed in the seventh basement \u2014 a room completely sealed for noise and heat containment. This characteristic, essential for the project, created a problem: there was no conventional route for medium-voltage cable passage to the test location.<\/p>\n<p>The client needed to validate the system before delivery, and schedule allowed no delays. The difficulty was structural: multiple basement levels, absent technical routes, and a generator enclosed in an environment designed to prevent heat, sound, or additional equipment entry or exit.<\/p>\n<p>The solution required rethinking the energy path. We used an alternative route through an area connected to ventilation ducts, conducting cables to the seventh basement. Meanwhile, the load bank, a 3.3 MVA assembly coupled with a 13.8 kV to 480 V step-down transformer, was positioned at the building entrance, still under construction, at the only point allowing adequate access and dissipation.<\/p>\n<p>Despite these difficulties, we managed to keep the test running stably. The entire operation was performed remotely from the plant&#8217;s monitoring room, guaranteeing safety, control, and continuity without physical presence at the main equipment.<\/p>\n<p>The test was completed within required parameters, proving operational capability even in a scenario with severe access and installation limitations. There are cases where infrastructure imposes complex barriers \u2014 that&#8217;s why planning precision and technical adaptation make testing viable.
