Improved technique to measure electronically AC losses in superconducting cables
Abstract
An improved electronic method for measuring ac losses in superconducting cables of lengths from 1m to 10m was developed. This method compensates for phase shifts in the measuring circuit elements and for imbalance of the difference amplifier due to changes in the common mode voltage. This measuring method is being further improved and adapted to the loss measurements of a 138V, 4 kA, 100 m long superconducting cable under construction.
