E isitsoe USA ka 2024, 1000 kVA enatse tharo-pase ea mekhahlelo-e kentsoeng ka transformere lumellana le IEEE Std C57.12.34-2022 mme e kopana le maemo a sebetsang hantle a matla a DOE 2016. E sebetsa ho 60 Hz ka motlakase o ka sehloohong oa 24 kV le motlakase oa bobeli oa 480GrdY / 277 V, o nang le sehlopha sa li-vector Dyn1. Transformer e sebelisa maqhubu a koporo le ho pholile ha KNAN, 'me e tletse oli ea ester ea tlhaho ea FR3 ho matlafatsa tšireletso ea mollo le ho boloka tikoloho. E na le tšebetso ea loop feed, e shoeleng-ka pele, le{16}}ha ho na{16}}changer ea ho roala thepa e fanang ka mefuta e fapaneng ea taolo ea voltage ea ±2 × 2.5%, yuniti e na le 5.75% impedance, ha ho{18}tahlehelo ea 1.020 kW, le tahlehelo e sebetsang ea{20,8,07} kabo ea matla a mahareng.
Transformer e shoeleng ea 1000 kVA e fokotsa kotsi ea arc flash nakong ea ts'ebetso kapa tlhokomelo. Mohaho oa eona o ka pele o shoeleng o kenyelletsa lihlahla tsa rabara tse sirelelitsoeng ka botlalo, tse emisitsoeng ka matsoele a mangata, ho netefatsa polokeho e ntlafetseng le boiketlo ba khokahano.
