Abstract
A system includes a high-current junction, a voltage sensor, and a controller. Power connectors of two components are electrically connected at the high-current junction, where a high current passes between the two components at the high-current junction. The voltage sensor detects a voltage at the high-current junction. The controller performs a predetermined action in response to the voltage sensor detecting the voltage at the high-current junction being greater than a predetermined threshold voltage. The system may be a data center rack. The high-current junction may be the junction at which an alternating current (AC) input receives AC power from AC mains. The high-current junction may alternatively be the junction at which a power supply receives the AC power from the AC input to generate direct current (DC) power to provide to data center rack components insertable within the data center rack.
