SuperPower adds new AC loss coil test facility

September 2, 2015


September 2, 2015 – Schenectady, New York – SuperPower Inc., a proud sponsor of the 12th European Conference on Applied Superconductivity (EUCAS 2015) being held in Lyon France, from September 6th to the 10th, will be a participating exhibitor highlighting its state‐of‐the‐art secondgeneration high temperature superconductor (2G HTS) wire, which is the enabling component for many energy‐efficient and power dense devices, each of which can benefit from unique wire specifications.

AC Loss Coil Test Facility

SuperPower has successfully completed the initial ac loss testing of a prototype Fault Current Limiter (FCL) Transformer HV winding module being developed in its FCL Transformer program sponsored by the US Department of Energy(Note 1). The HV winding module was tested in SuperPower’s new calorimetric ac loss coil test facility. The ac loss coil test apparatus was developed to determine the ac losses developed in prototype winding modules and to enable the ability to look at the impact on ac losses of different winding configurations and 2G HTS conductor architectures. The calorimetric ac loss measurement system is LN2 based and can handle coils up to 850 mm diameter and 600 mm height and losses from a few watts to up to 1500W.

The non‐metallic FRP Dewar used in the system was developed in conjunction with Fabrum Solutions, LLC and is optimized for low background heat leak and mitigates any eddy current losses. In addition to characterizing coil structures for FCL Transformer applications, the test system will be a valuable tool for future evaluation of the ac loss characteristics of other coil structures for applications such as motors/generators, cables and standalone FCLs.
