Abstract: The invention contemplates a technique for providing loop control on a faulted overhead or underground loop system, while preventing restored current from being fed or back fed into the fault. In particular, the invention provides a method, device, and system for restoring power to a faulted loop distribution system. The inventive method includes detecting a fault on the loop distribution system, interrupting current on the faulted part of the loop distribution system, isolating the faulted part of the loop distribution system from an unfaulted part of the loop distribution system, restoring current to the unfaulted part of the loop distribution system, and preventing the current from flowing to the faulted part of the loop distribution system. The method may further include providing the current to a load.

The gear assemblies adapt a racking device of the circuit breaker so as to be operable to rack the circuit breaker within the cell of the switchgear system.

Abstract: The present invention is directed to a system and method for monitoring the performance of a heat exchanger. In accordance with the system and method, baseline values of a performance factor (E) for baseline sets of heat exchanger operating values are calculated and stored. A current value of E is calculated for a current set of the operating values and is compared to a retrieved baseline value of E for a baseline set of the operating values that at least substantially matches the current set of the operating values. E provides a measure of the performance of the heat exchanger and is calculated using differential temperatures across the heat exchanger and without using any information concerning the physical construction of the heat exchanger.

Abstract: A fuel cell is placed in parallel with a battery via a mechanical switch. The voltage is held nearly constant by the battery and the power flow is controlled by adjusting the fuel cell operating parameters (such as temperature or air flow) and by opening and closing the mechanical switch. The result is a system that operates at nearly constant voltage without the need for an expensive power conditioning system. The output of the system can then be processed via a traditional power conditioning system such as an inverter or dc-to-dc converter without the need for a wide range of input operating voltages. This reduces the cost and size of the fuel cell power conditioning system.

Abstract: A system and methods that enable a restoration scheme for power distribution systems that is independent of power distribution system component configuration, the number of power distribution system components, and component settings are provided. In a power distribution system, a number of intelligent reclosers having restoration control modules are deployed that execute a restoration scheme. The intelligent reclosers constantly poll cooperating power distribution lines to determine changes in current or voltage provided by the power distribution lines. In the event of a power distribution system fault, the reclosers act in accordance to a predefined restoration scheme to reanimate the unaffected portions of the failing power distribution system.
