Re: [TCML] BIG solid state

Hi Vasil,
Actually, a common benchmark that spark-gap coilers have used for many years is about '1kW per foot of arc.' The Freau equation suggests that as the coil size increases this linear relation should become harder to maintain, but it is still fairly easy to reach at the 25kVA mark. -GL

What a beast, this is the DRSSTC at its own best! It proves



that DRSSTC systems can be scaled up with high efficiency, and



they win compared with "those old spark gappers" isn't it?

Hoping to see more details of the machine.

Best coiling
