摘要： A power delivery system for data center. Servers are divided into server clusters, and each server cluster is served by multiple power source with multiple inputs from a power supply module. Each power supply module includes a local bus and a local controller which controls connections on the local bus to deliver utility power to its assigned server cluster or backup power to any of the server clusters. Each of the power supply modules has a battery storage system with switchable connections to the local bus and to an inter-system bus, and a PV system with switchable connections to the local bus and to an inter-system bus. The battery storage system may be charged from the utility power or the PV system. The inter-system bus is connected to all of the server clusters, such that power flowing in the inter-system bus can be delivered and dispatched to power any server cluster.

摘要： A power management system includes a generator, a meter mounted transfer switch, and a power management module. The generator includes a controller positioned in the housing of the generator. The generator connects to the power management module to provide power to one or more electrical loads. The controller is configured to selectively disconnect at least one of the electrical loads by communicating, via a wireless gateway, to a transfer switch of the power management module to move between first and second positions for connecting the generator to the one or more electrical loads.

摘要： A method for loose joint detection in medium voltage switchgears with busbar joints, circuit breaker upper and lower spouts, and cable connection joints, arranged in an air insulated housing, and medium voltage switchgear itself, in order to create an effective loose joint detection with lower operating expense, but with high performance and accuracy, involves measuring actual temperatures at a first phase as a first temperature (T1), at a second phase as a second temperature (T2), at a third phase as a third temperature (T3), at predefined critical points, such as at the busbar joints, and/or at the circuit breaker upper spouts, and/or at the circuit breaker lower spouts, and/or the cable connection; and comparing temperatures in a logical dependency Ti>(Tj+dT), with i≠j, permuted with i from 1, 2, 3, and j from 1, 2, 3, and setting the alarm if the logical dependency is fulfilled.
