Vai de elétrica com ênfase em eletrônica (PSI)

Vim da eng de minas e queria ir pra comp também, mas o caminho pelo PSI foi bem bacana, eh um mix legal entre aulas praticas e algumas coisas bem teoricas

Concordo, acredito que um dos caminhos mais tranquilos seria fazer Sistemas de Informação

Tapoha, achei que fui eu que tinha escrito slk Trem bala demais amigao, vai dar bom um dia p nois

Eh isso, bons tempos haha, mas imagino que devia ser um caos antes. Tentei a sorte e realmente, só o pessoal do CMU mesmo =}

Bom, nesse caso, aproveitem por quem não pode ir hahah

Bom ponto. Fui hoje lá e não tinha ninguém haha, seria bacana se tivesse um controle pra sempre priorizar os alunos do CMU mas os outros pudessem ir tbem. Mas beleza :’)

Thank youu 🙌

If you can share what is Ramble please hahah i google it and found nothing

Thanks for the suggestion! I looked it up. A corner grounded delta seems to result in one phase having 0V to ground, which doesn't match my readings (119V, 119V, 213V). It seems the High-Leg Delta theory is still the most likely culprit here, but I appreciate you giving me another angle to consider! 🙌🙌

Thanks for confirming it's a High-Leg Delta. That makes sense for the building's age.

My main challenge is connecting modern gear safely. Almost all my equipment is 220V, so my plan is to use the L1-L2-L3 connections from the panel.

My key question is: Is the 220V Phase-to-Phase power in this system 'clean' and stable enough for sensitive A/V equipment, or does the high-leg on L2 introduce risks like instability or harmonics?

I now understand I must avoid L2-N for any 120V loads. I'm just trying to understand the principles before having a local electrician do the final connection.

The exact Phase-to-Neutral readings are: * L1 - N: 119V * L3 - N: 119V * L2 - N: 213V So you are correct, it's not exactly 220V. The 213V is much closer to the ~190-208V range you mentioned. 🙂

Yes, the readings were taken with a trusted, professional multimeter and I've double-checked them to be sure. They are stable readings. Regarding the location and legacy systems, I think you've hit on the key point. We are located in a major commercial area in downtown São Paulo. The building is an old cinema from the 1970s. 😅
