Resistance Measurement PlanMechanical TF Joint Test System

• Mechanical Prototype Testing– Cyclical Mechanical Loads Applied to Prototype Joint

– Measure Joint Voltage Drop with 100 Amperes Applied

– Voltage Measured at Two Joint Locations

– Automated Test Stand Control & Data Acquisition

• Joint Voltage Drop Accuracy Factors– Limited by Cycle Time

– Initial Investigation Indicates 0.5% Should be Possible

– Cycle Dwells Could Increase Accuracy to 0.2% or Better
