摘要： A short circuit detection circuit for an electrical circuit includes a secondary power supply. The electrical switch is connected in series with a load and is selectively connected in series with a first power supply. The secondary power supply is limited in comparison to the first power supply in terms of voltage and/or current. A first resistance is electrically connected between the secondary power supply and a first terminal of the electrical switch. A voltage measurement circuit measures a voltage at the second end of the first resistance. A controller is configured to, while the electrical switch is controlled to an open state, energize the secondary power supply and obtaining a first voltage measurement. In response to the first voltage measurement indicating that a voltage across the first resistance is greater than a predetermined threshold, the controller identifies a low-resistance condition in the electrical switch.

摘要： Systems and methods for verifying correct completion of a power control sequence in a switchgear provide a commissioning agent that can automatically verify correct completion of the power control sequence. The commissioning agent includes a sequence verification tool that can initiate performance of a power control sequence in the switchgear and immediately compare the sequence actually performed to the sequence intended to be performed. If the two sequences do not match in order and timing, the verification tool reports the mismatch and identifies the error. In some embodiments, the commissioning agent further includes a log viewer that captures the sequence actually performed in the switchgear and displays the result for viewing. Such an arrangement provides a faster and more reliable way to double-check the system integrity of the switchgear during initial engineering and after factory and/or field modifications.

摘要： According to aspects of the disclosure, a method and system are provided for transferring a load between a primary power source and a secondary power source. In accordance with the disclosure, a method of transferring a load between a first power source and a second power source includes analyzing a plurality of power sources to identify one or more power sources providing a power greater than a threshold value. The method also includes selecting a power source from the identified one or more power sources providing power greater than the threshold value. The method further includes connecting the selected power source to a transfer mechanism. The method still further includes actuating the transfer mechanism, using power provided to the transfer mechanism by the selected power source, to transfer the load from a connection with the first power source to a connection with the second power source.

摘要： A method for applying extended reality to simulate an actual flow system, including receiving selection of simulated components of the actual flow system that are graphical elements, receiving component metadata for each simulated component that represents simulated component factors that affect the simulated flow from, through, or to the simulated component, receiving simulation connection metadata for each simulated connection between the simulated components that represents simulated connection factors that affect the simulated flow through the simulated connection, receiving actual data over time, simulating the flow over time through the simulated connections based on the actual data by applying a model using a set of operations to the actual data, the simulation component metadata, and the simulation connection metadata. The method further includes displaying via the extended reality user interface the three or more simulated components as connected by the simulated connections and the simulated flow.

摘要： Example devices and methods for compensating for monitoring a surge protection device are provided. In some embodiments, a device is configured to couple to a surge protection device. The device comprises a processor that is capable of sending a DC current signal. A serial data interface is electrically connected to the processor and includes at least one shift register. The device also comprises a multiplexer coupled to the serial data interface. The serial data interface is operable to direct the DC current through the multiplexer. The device also comprises an analog to digital converter (optionally embedded within the processor) that is operable to output a digital signal corresponding to a voltage induced by the DC current signal. Returned DC signals represent surge protection device's health and a multitude of other surge module information.

摘要： A method and system are provided for transferring a load between a primary power source and a secondary power source. In accordance with the disclosure, a controller senses, via a sensor, an electrical signal providing power from the primary power source to the load. The controller also detects a non-conforming power event by determining that a parameter of the electrical signal is either more or less than a first threshold value. Responsive to the detection of the non-conforming power event, the controller determines a quantity of non-conforming power events that occur during a first time interval. The controller further can compares the determined quantity of non-conforming power events to a second threshold value. Responsive to the determined quantity of non-conforming power events being either greater or lesser than the second threshold value, the controller initiates a control signal, such as a control signal to initiate a load transfer.
