to NSTXU Test Cell |
Neumeyer |
The
TF circuit is to be changed from four parallels to eight parallels to meet
the upgrade requirement of 130kA. Eight 1/c-1000 mcm cables are proposed to
be used in each leg of the TF circuit for the run from Transition
Area to the NSTX Test Cell. |

Suppress and Bypass Coil and Busbar
DLF |
Titus |
The purpose of this calculation is to
quantify the dynamic response to a suppress and bypass initial over-current.
This effect is evaluated for a typical (PF1aU) bus bar response and the
response of the coil to the current increase over the nominal operating
current as the coils are shut down. The intention of this calculation is to
determine if the overcurrent loading from the suppress and bypass must
additionally address a dynamic increase from the mechanical response. |
