INTRODUCTION
Increasing power demand and variability of power supply - Need of energy storage devices in power system
SMES - fast and efficient energy storage system – operation at cryogenic temperature
MOTIVATION
Direct cooling- no requirement of metallic parts for conduction
Practical cases: Conduction cooling- metallic parts to transfer heat

Poster paper size: A0
841 x 1189 mm (33.1 x 46.8 inch)
Coil excited by 90 mA at 42 Hz
LCR meter - 10 mΩ to 200 MΩ
- 16 nH to 750 kH
Do not give too many figures. Only representative figures should be given relevant to your results.
CONCLUSIONS
For coil with conducting former, the inductance variation with temperature occur prominently for coil with conducting former.
