A Novel Differential High-Frequency Current Transformer Sensor for Series Arc Fault Detection
Fault arc detection is an important technology to ensure the safe operation of electrical equipment and prevent electrical fires. The high-frequency noise of the arc current is one of the typical arc characteristics of almost all loads.

Voltage transient management for Alternating Current trains with vacuum circuit breakers
Alternating current power supplies and rolling stock with 25 kV (50 or 60 Hz) and 15 kV (16.7 Hz) traction systems do not have the characteristics and behaviour of a typical three‐phase medium‐voltage distribution system. Switching inductive loads with a

Transformer Grammars: Augmenting Transformer Language Models with Syntactic Inductive Biases at Scale [PDF]
We introduce Transformer Grammars (TGs), a novel class of Transformer language models that combine (i) the expressive power, scalability, and strong performance of Transformers and (ii) recursive syntactic compositions, which here are implemented through

Improving the Electricity Quality by Means of a Single-Phase Solid-State Transformer
The paper describes the use of a single-phase three-stage solid-state transformer in networks with non-sinusoidal voltages in order to improve the quality of electricity. An active-inductive load was chosen as the load.

Influence of transformer leakage inductance on DC high current generator
Abstract The efficiency is affected by the parameters of components in the DC high current generator. The leakage inductance of the rectifier transformer will affect the output and filtering effect of the device and reduce the power quality of the public network. To improve the output and filtering effect of the DC high current generator,
