High-voltage switchgear refers to electrical equipment operating within a voltage range of 3.6 kV to 550 kV, used in power generation, transmission, distribution, energy conversion, and consumption systems for switching, control, or protection purposes. It primarily includes high-voltage circuit breakers, high-voltage disconnectors and earthing switches, high-voltage load switches, high-voltage auto-reclosers and sectionalizers, high-voltage operating mechanisms, high-voltage explosion-proof swi

What is SST?SST stands for Solid-State Transformer, also known as Power Electronic Transformer (PET). From the perspective of power transmission, a typical SST connects to a 10 kV AC grid on the primary side and outputs approximately 800 V DC on the secondary side. The power conversion process generally involves two stages: AC-to-DC and DC-to-DC (step-down). When the output is used for individual equipment or integrated into servers, an additional stage to step down from 800 V to 48 V is require

With the increasing demand for transparent/flexible displays, healthcare sensors, and robotics, there is a need to advance the development of thin-film transistors (TFTs) manufacturing and large-scale circuits. This paper has proposed an IGZO-TFT-PDK to aid the educators and research community to explore the circuit design space of dual-gate IGZO-TFT devices. To solve the tensile force-induced current variation problem in IGZO-TFT devices, an omni-directional device and its layout template with

Target detection and field surveillance are among the most prominent applications of wireless sensor networks. However, the sensing capabilities of sensors are affected by environmental factors in real deployment. This paper investigates the problem of detecting probability in a log-normal shadow fading environment. It presents an analytic method to evaluate the detection probability by at least k sensors under practical considerations. Furthermore, we also shows that shadow fading makes signifi
