Transrex 500 kW Power Supply Transductor Upgrades

This paper describes various upgrades and tests done at the Research Division 500 kW Transrex power supply de current transductors and chassis. The results of all modifications were measured on the same test setup with the same transductor head and chassis. The setup used for the measurements is shown in Fig. 1. Field testing of over one-hundred power supplies indicated that the results given in this paper are similar to the signals observed in the field within a factor of + or - two. The de transductors yield 10Vdc burden resistor voltage at 5000 A load current.
