Re: Resonating A & C phase loads in 3PH

Hello Hector, do not we want to commit ourselves to the diode plug?

I have used MOTs as reactors and have to say that adjusting them is very hard as they have little room for extra turns and they will be warm. It is of course a cheap alternative if you have nothing else, I got one as a gift and the other from the junkyard.

I have here an old sst250 / 10e variable transformer for 2.5 kva which can be adjusted wonderfully. Instead of a transformer, I used the as adjustable reactor. You can clearly see the change on the scope when you stop the transformer I'm trying to get another 2 of them. These transformers are very heavy have a high inrush current, in my opinion, the optimal magnetic memory for the diode plug.

The efficiency has increased tremendously due to the large transformers but adjusting them precisely over the turns is very difficult.

Just calculate the capacitors via the reactance. The next day I had different values. Of course, the mains frequency may be lower or higher, which of course would falsify the measurement results.

I am very grateful for ideas and feedback.

regards

Sven
