Abstract
A power distribution system is provided comprising a power regulator, a battery circuit, and a battery monitoring system. The power converter is provided for converting AC power to DC power and for providing DC power to a load. The battery circuit is coupled to the power regulator and the load and is operable to recharge by receiving DC power from the power regulator. The battery circuit is also operable to supply DC power to the load when there is an interruption of power from the load. The battery monitoring system comprises a field measurement device located in close proximity to the battery circuit, the field measurement device including an input mechanism for receiving current measurement data and an analog-to-digital converter for digitizing the received current measurement data. The battery monitoring system further comprises a monitor located remotely from the field measurement device, the monitor including a first communicator for receiving digitized data from the field measurement device.
