The measurement of ripple current in battery plants

A draft of a standard for the selection of batteries for UPS (uninterruptible power supply) applications is being written to address the application problems including the reduced-life phenomenon. In looking for a cause for accelerated battery wear-out, the author studied the electrical environment to identify the differences between the relatively recent UPS applications and the older telecommunications applications. The author describes the data acquisition system, the data reduction procedure, and the instrumentation used. The problem of standardizing the measurement techniques and procedures is discussed.<
