- This paper describes the electrical design and mechanical construction of a 50 kA step switched'' battery bank. Individual fuses protect each of the forty parallel isolated strings of three series (12 V) batteries. Step current waveforms of 12.5 kA, 25 kA, 37.5 kA, and 50 kA are produced by 8 sets of pneumatically driven 20 pole step switches and current limiting stainless steel trombone'' resistors. Inexpensive, yet conservatively designed, Group 65 Motorcraft car batteries are used to give an I²t capability of better than 5 × 10⁹. The battery bank has well over 1500 shots, with testing of commercial switchgear continuing. In addition to the battery bank engineering data, results of repetitive testing of vacuum interrupters at their I²t limit will be provided. 8 figs.
