Abstract: The present disclosure is a system and method for measuring AC residual current and DC residual current using a singular type-B residual current monitoring device. The system includes a sensor comprising two or more cores that measure residual AC current and residual DC current from two or more current carrying conductors through the cores that carry AC current and DC current. The system includes a controller that sends both an AC excitation current to the cores, as well as a DC nulling current that cancels out the DC residual current, allowing the system to then accurately measure the AC residual current. The system also includes a self-test feature that injects known quantities of both AC current and DC current through the sensor to determine if the sensor is functioning properly.

Abstract: A device for detecting a coating applied to a surface includes a portable housing, a light source, a light detector, and a processing unit. The light source emits a first light having a first wavelength. The coating includes a fluorophore that re-emits a second light having a second wavelength, which is different than the first wavelength, in response to excitation by the first light. The light detector receives the second light re-emitted from the coating. The processing unit is adapted to determine a re-emission intensity of the second light and to determine a coverage metric of the coating based on the re-emission intensity of the second light. The coverage metric is then used to infer the efficacy of the coating.

Abstract: The present disclosure is a system and method for virtualized energy metering. The virtualized energy metering is performed via a power distribution system including power modules that include voltage and/or current sensing circuitry. Each power module may include a processor unit configured to transform incoming analog signals into time-correlated digital data. The data captured by a first power module may be sent to a second power module that further analyzes and/or aggregates the digital data and reports out the analyzed/aggregated data to a user, including aggregated energy-related parameters. The system and method may facilitate the efficient sensing, measurement, and calculation of energy metering parameters, with greater optimization of monitoring resources, reduced complexity of hardware, and lower solution costs.

Abstract: The present disclosure is directed to a rack power distribution unit (RPDU) that automatically and safely switches power to one or more receptacles. The RPDU includes one or more processors utilizing control algorithms that manage bistable relays so that in-rush current is minimized upon manual connection/disconnection of power to a load device. In particular, relay contact status (open/closed) is identified based on changes in RMS or peak voltage influenced by the load impedance. The RPDU is also configured to predict timings for voltage zero-crossing events. In this manner, and based on the determination of relay contact status and voltage zero-crossing prediction, open relay contacts are identified and safely closed at voltage zero-crossing.
