A dual power source pulse generator in power connection with a pair of electrodes having a first electrode, a second electrode and an air gap therebetween. The dual power source pulse generator includes a first pulse source producing a high voltage low current pulse across the pair of electrodes to allow dielectric breakdown, and a second pulse source electrically connected in parallel with an output of the first pulse source, and producing a low voltage high current pulse to thereby produce a current flow of high-density plasma between the same electrodes of the pair of electrodes in response to the high voltage low current pulse.

An energy management system includes a module for an energy consuming device. The module has a module main controller including a computer processor in communication with a module computer readable storage medium containing computer executable code. When the computer executable code is executed by the computer processor, it performs a method including determining whether a demand state is a peak demand state, employing a reduced operational mode of the energy consuming device during a peak demand state, and employing a normal operational mode of the energy consuming device during a demand state other than a peak demand state. In an embodiment, the system also includes a system main controller in communication with the module.

An energy management system manages energy consumption of managed device(s) disposed to receive energy via a meter connected to an energy supply, the energy supply. A system controller has a computer processor that instructs the managed device(s) to employ an operational mode based on the priority, the energy need, the demand state, and whether the energy consumption rate of the managed device(s) exceeds energy available from at least one of the external energy source and internal energy source.

A method and apparatus for a circuit breaker having an arc fault detection circuit, a ground fault detection circuit, a signal indicative of an arc fault in a corresponding pole of the circuit breaker; and a trip mechanism including a pair of separable contacts. The trip mechanism is in operable communication with the ground fault detection circuitry so than in response to receiving the signal from the ground fault detection circuitry, the arc fault detection circuitry causes the ground fault detection circuitry to generate a trip signal causing the trip mechanism to separate the pair of separable contacts.

Charging stations for use in charging an electrically powered vehicle and related methods are disclosed. One example charging station includes a housing having an interior. The housing is configured to enclose at least one vehicle charging component and defines a receptacle opening. The charging station further includes a first receptacle configured to receive a charging connector. The receptacle includes a front portion and a back portion. The back portion of the first receptacle includes a first drain port configured to permit a fluid flow to drain from the first receptacle. The first receptacle is configured to be positioned at least partially within the first receptacle opening, such that the back portion of the first receptacle is positioned within the first enclosure. The first enclosure defines a first drain opening configured to permit fluid from the first receptacle to an exterior of said first enclosure.

A load shedding system for operating at least one circuit breaker positioned within an enclosure is described. The load shedding system includes a processor configured to receive a demand signal and to provide a predetermined load shedding signal. The load shedding system also includes at least one load shedding apparatus configured to receive the load shedding signal from the processor. The load shedding apparatus is configured to be coupled to a door of the enclosure. The load shedding apparatus is further configured to be operatively coupled to the at least one circuit breaker and further configured to actuate the at least one circuit breaker in response to the load shedding signal.
摘要:
A controller for a power system including a plurality of power system components includes a memory for storing computer-executable instructions and a processor configured to execute the computer-executable instructions. The computer-executable instructions program the processor to determine an operating condition of at least one first power system component and at least one second power system component of the plurality of power system components. The processor is also programmed to determine whether a predetermined condition is met based on at least one operating condition, and transmit a command to at least one other controller to at least one of electrically couple the first power system component to the second power system component and electrically decouple the first power system component from the second power system component based on whether the predetermined condition is met.
