Supraleitfähigkeit - Teil 13: Messung der Wechselstromverluste - Magnetometerverfahren zur Messung der Hystereseverluste von supraleitenden Multifilament-Verbundleitern (IEC 61788-13:2012); Deutsche Fassung EN 61788-13:2012
Overview
This part of IEC 61788 describes considerations for the measurement of hysteretic loss in Cu/Nb-Ti multifilamentary composites using DC- or low-ramp-rate magnetometry. This International Standard specifies a method of the measurement of hysteretic loss in multifilamentary Cu/Nb-Ti composite conductors. Measurements are assumed to be on round wires with temperatures at or near 4,2 K. DC or low-ramp-rate magnetometry will be performed using either a SQUID magnetometer (superconducting quantum interference device) or a vibrating-sample magnetometer (VSM). In case differences between the calibrated magnetometer results are noted, the VSM results, extrapolated to zero ramp rate, will be taken as definitive. Extension to the measurement of superconductors in general is given in Annex B. The responsible committee is K 184 "Supraleiter" ("Superconductors") of the DKE (German Commission for Electrical, Electronic and Information Technologies) at DIN and VDE.
