Faulty line detection for cross‐line same‐phase successive ground faults in distribution network based on transient characteristics

IET Generation, Transmission & Distribution
Currently, theoretical analysis of single‐phase grounding (SPG) faults in low‐current grounding systems has reached a high level of refinement, and the corresponding detection methods have matured.

Faulty feeder detection based on transient attenuation and waveform similarity for low-resistance grounded system

International Journal of Electrical Power & Energy Systems
In the case of a single-phase high-impedance fault (SPHIF) in a low-resistance grounded system (LRGS), the weak fault current makes it difficult to accurately detect the faulty feeder. To highlight the fault features, this paper first defines the concept

STDweb: simple transient detection pipeline for the web

Acta Polytechnica
We present a simple web-based tool, STDWeb, for a quick-look photometry and transient detection in astronomical images. It tries to implement a self-consistent and mostly automatic data analysis workflow that would work on any image uploaded to it, allowing to perform basic interactive masking, object detection, astrometric calibration of the image ...

Strategy for Identifying Vera C. Rubin Observatory Kilonova Candidates for Targeted Gravitational-wave Searches

The Astrophysical Journal
Since the observation of the binary neutron star merger GW170817 and the associated kilonova AT2017gfo, the next joint gravitational-wave/optical kilonova has been highly anticipated. Overlapping observations between the Vera C. Rubin Observatory and the

Flaring Stars in a Nontargeted Millimeter-wave Survey with SPT-3G

The Astrophysical Journal
We present a flare star catalog from 4 yr of nontargeted millimeter-wave survey data from the South Pole Telescope (SPT). The data were taken with the SPT-3G camera and cover a 1500 deg ^2 region of the sky from 20 ^h 40 ^m 0 ^s to 3 ^h 20 ^m 0 ^s in ...
