Improvements in efficiency, power density, power monitoring, and reconfigurability have been recently achieved in data center power distribution. The past techniques of massive transformer-based power distribution units feeding under-floor hardwired circuits are shown to be obsolete. Discover here the newer approaches to power distribution including modular power distribution and overhead power busway. Study their advantages compared to the legacy approach.
