    Hello I'm new to electronics so can some one please tell my magnet type alternators in cars would an transformer reduction work to 220v ? I mean can the stator leads 3phase by used to connect to an transformer 3phase to 2phase transformer I'm worried about high frequency I wanted to use external indisti type bridge rectifiers so I'm worried about over loading the stator leads inside the alternator just to run small projects .Preciseli I'm just looking at independent ignition system for an 4 cilinder engine with out baterry problems Basicali. So Hoppe some one did similar project in the past. I also want to use that magnet type alternator for back up in case I need inverter to run small machines or light bulbs when power is cutt off. So Hoppe for some sugestions ? I heard an solar panel regulator could by used so I'm not Shure if that would work or not .I'm mostli concerned about stator leads,over drag Hoppe to not brake pulley to engine connection and would avoid engine lagg from over load .

    Why do we take 180% of the fault current on the low-side and reflect it to the high-side for 50P? It seems like we're taking extra steps. Couldn't we just take 180% of the maximum high-side fault current based on the transformer size?

    Could you explain or make a video on open phase faults and sequence components. I have a very hard time finding material on when a phase opens but isn't connected to ground or another phase. If this happens, I'm curious on the symmetrical components and what they look like.

    Just now i noticed my ETAP 16 is malfunctioning. For protection coordination, whatever values i enter in the differential relay properties box, vanishes once i press OK button. This happens for CT ratings too. When i tried to disable overcurrent protection, the same happened. Unable to set breakers to open. Everything works first. When i reopen the properties box, nothing is there. Everything is in the default value. And so breakers are not opening. What goes wrong.?

    Is 150% common for pick up current? I am used to seeing 125% on low voltage.

    • @Whitetooth1030
      @Whitetooth1030 Месяц назад

      125% is normal, 150% is more of this Engineers decision. Some Engineers add more percentage because they want to be 100% sure they don’t trip any operational load current.

    • @romeroengineering
      @romeroengineering 2 месяца назад

      Hi. CTs should always look into the protected equipment and encompass the interrupting device. For example, the CTs for the transformer differential relay in this example should be on the top side of the high-side circuit breaker and bottom side of the low-side circuit breaker, both looking into the transformer. The CT on the main breaker for the bus differential relay should be on the top side of that breaker, therefore overlapping with the CT for the transformer differential relay. Hope this helps. -Ricardo.
