Re: Different secondary design ?

Hi Jeroen,

        You could do it but the secondary losses are only about 1% of the
total system losses, so I have heard. The losses from the spark gap dwarf
the losses from the secondary form. Terry worked this out a couple of months
ago. Rhienhard also has done a lot of work in this area. Check the archives
for "secondary form losses". It would look nice though and save weight, but
you might still be at risk from internal arcovers if you left the ends open.
Just my two cents.
