The source is a 3 phase 5 wires 220 source..
Is a sorensen power supply that can supply 120 amp but I only supply 60 amps to semiconductor diodes connected in series..... But sometimes goes to a max current and this destroy the load..
I have a power supply running 60 amps to the load.
What are the chances of lightning(storm)creates a huge spike in the load.I checked the load and it was destroy, butthe power supply is working ok.What causes this spikes in this power supplies.
