Webinar nr 9 Arc Flash 2022 - DC Systems
It took me two failed attempts (audio issues) for live event and I decided to record webinar and share it with all of You here. First of all great thanks for patience and joining me today. I hope this will be useful time spent on why we are looking at DC systems form arc flash point of view.
Lets check first what systems we use:
What difference it makes ?
It has changed during years but we are going back to DC systems. It might be partially as EV cars or with HVDC links. Generally speaking DC current is harder to disconnect than AC as presented by ExperimentRobert33 ?? This is solved now and we can handle it but we still see it is very easy to sustain arc flash even at low DC currents (PV). So lets have a look at it form personal safety and arc flash point of view.

2 年Thanks again Marcin Ruta, this topic also applies to PV/home battery installations most of the consumers are not aware of the risks that DC systems bring. Sharing knowledge is key in these matters!

2 年feel free to share you questions regarding DC arc flash hazard. I was for example, surprised with EV cars fires after Ian Hurricane in Florida. I think they report few fires of cars after saltwater corrosion of cells. It will be interesting to see more details about it.
