Abstract: Managing power feeds includes monitoring a waveform of a high-voltage power feed supplied to an electrical load to detect potential interruption of the high-voltage power feed and switching to another power feed to supply power to the electrical load in response to identifying the waveform pattern. Monitoring a waveform includes processing the waveform to determine if one or more waveform patterns are present in the waveform. A waveform pattern indicates, by its presence in a waveform of a power feed, a power event associated with the power feed, and some waveform patterns indicate potential interruption of the power feed. Switching to another power feed in response to determining potential interruption of the power feed based on waveform monitoring enables an uninterrupted power supply.

Abstract: A reserve power bus ring links multiple reserve power systems to computer systems in a data center. The reserve power bus ring enables multiple reserve power systems to concurrently provide reserve power support to sets of computer systems. The reserve power bus ring includes portions to which one or more reserve power systems and computer systems are coupled, and isolation devices collectively isolate particular portions of the reserve power bus ring in response to a fault condition in that particular portion, such that that computer systems on other portions of the ring continue to receive reserve power support from the reserve power systems coupled to the remaining portions. A reserve power bus ring may include respective power buses coupling two or more reserve power systems on an upstream side and a downstream side, and isolation devices can break a connection of the power bars to isolate the reserve power systems.
