Summary of Results from Special PLI2 Testing on RB A78 Conducted on 03/10/2009

The special PLI2 test on RB A78 was performed on October 3, 2009, from 20:35 to 23:50. The current steps included 0.76A, 1.2A, 1.6A, and 2.0A, with a ramp rate of 10A/s and plateau times exceeding 10 minutes. Data files captured during the test include analyses on bus segment resistance, noise characteristics, and normalized resistance for multiple segments. Special attention was given to the measurement of excess resistances and standard deviations of voltage. Results and data are organized for thorough analysis.
