As IOT develops drastically these years, the application of cloud computing in many fields has become possible. In this paper, we take low-voltage current transformers in power systems as the research object and propose a TCN-BI-GRU power measurement method that incorporates the signal characteristics based on the transformer input and output. Firstly, the basic signal enhancement extraction of input and output is completed by using EMD and correlation coefficients. Secondly, multi-dimensional feature extraction is completed to improve the data performance according to the established TCN network. Finally, the power prediction is completed by using BI-GRU, and the results show that the RMSE of this framework is 5.69 significantly lower than other methods. In the laboratory test, the device after being subjected to strong disturbance, its correlation coefficient feature has a large impact, leading to a large deviation in the prediction, which provides a new idea for future intelligent prediction.

The National Training Center (NTC), a prominent source of on-location and virtual classroom training and training materials in the various low-voltage disciplines, is offering a quick flash sale of its renown Low Voltage Library.  

To be clear at the beginning of this article, determining the cross-section of conductors and cables is, for sure, not the most exciting part of electrical design. There are much more challenging and more exciting parts than staring at endless... Read more

A high voltage full wave rectifier and doubler circuit having complementary serially connected low voltage MOSFET stacks to provide high voltage capability. The state of the MOSFETs in the MOSFET stacks is controlled by means of resistors coupled between the circuit's outputs and a time varying input signal. The resistance values of the resistors are selected to maintain operation of the stacked MOSFETs below their breakdown voltages.

Apparatus and methods are disclosed related to low-voltage radio transmitters with high spectral purity. One such apparatus includes a baseband path with a predistortion stage, a programmable filter, and an upconverter core. In an embodiment, the programmable filter is placed between the predistortion stage and the upconverter core. In an embodiment, the programmable filter is configured by a controller to reject out-of-band noise introduced at the predistortion stage or earlier.

A cabinet structure for a switchgear assembly. The cabinet structure includes a cabinet having upper and lower vents and a breaker cradle for holding a circuit breaker having primary disconnects for connecting the circuit breaker to bus bars. The cabinet further includes an air passageway located between the upper and lower vents, wherein the air passageway extends vertically through the primary disconnects and the cabinet. Further, the cabinet includes a fan module having at least one fan for drawing outside air through the lower vent, the air passageway and the primary disconnects for cooling the primary disconnects.

A system and method are disclosed for level shifting a DDC bus with a low voltage loss. A pull up circuit includes an NMOS transistor, a PMOS transistor and resistor. An NMOS pull up gate is also included in line with the DDC bus. When powered, the level shifter adjusts the voltage of transmitted signals to match the voltage of a receiving device. The resulting adjusted is slightly lower due to a threshold voltage lost across one or more transistors. Additionally, when unpowered, the level shifter releases the signal transmission line. Unadjusted signals can then be transmitted without consumption of power by the level shifter.
