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 […]
