One Year Old

Somewhere around a month (or two) ago Machine2Wireless quietly passed through its first year of existence. It was quiet because we were busy. It is sometimes useful to look back in time to take stock of what has transpired, especially if one hopes to learn and grow from past experience. […]

The First All New Resonant Line in Thirty Years

NOTE: Submitted to CARTS 2014 Introduction The resonant line technique began at MIT Electrical Insulation Laboratories during WWII. The method satisfies a basic need to measure low losses in large reactive loads. The technique is to cancel the reactance of the load with a known (calculable) reactance, leaving the losses […]
