Partial discharge characteristics of an air gap defect in the epoxy resin of a saturable reactor under an exponential decay pulse voltage

High Voltage, 2020
Saturable reactor insulation is currently stressed by an exponential decay pulse voltage under normal operating conditions. The partial discharge (PD) characteristics of epoxy resin under an exponential decay pulse voltage were studied here and were ...

Model and Data Hybrid Driven Approach for Quantifying the Meteorology-Dependent Demand Flexibility of Building Thermal Loads

CSEE Journal of Power and Energy Systems
Recently, the heat and electricity integrated energy system (HE-IES) has become a hot topic in both industry and academia. In the HE- IES, the potential flexibility of the buildings' thermal loads can be exploited to relax the heat power balance ...

Architecture of a microgrid energy management system

, 2011
In the framework of deregulated electricity markets, distributed generation and load management are emerging as new technologies. In this context, the microgrid concept adds value to distributed energy resources (DER) by aggregating them into autonomous ...

From distributed tracing to proactive SLO management: a mini-review of trace-driven performance prediction for cloud-native microservices

Frontiers in Computer Science
Cloud-native microservices improve development velocity and elasticity, but they also create complex and dynamic service dependencies. Resource contention, queue buildup, and downstream slowdowns can propagate through call chains, amplifying end-to-end ...

AC flashover performance of different shed configurations of composite insulators under fan-shaped non-uniform pollution

High Voltage, 2018
Currently, it is founded that under unidirectional wind and certain landform, composite insulators are always fan-shaped non-uniformly polluted. In this paper, artificial pollution tests on three types of composite insulators with different shed ...

Power Allocation for Secure SWIPT Systems With Wireless-Powered Cooperative Jamming [PDF]

IEEE Communications Letters, 2017
This paper considers wireless-powered cooperative jamming (CJ) to secure communication between a transmitter (Tx) and an information receiver (IR), in the presence of an energy receiver (ER) which is termed as a potential eavesdropper. The full-duplex jammer harvests energy from the Tx's information signal and transmits jamming signal at the same time,

Measurement of Line-to-Ground Capacitance in Distribution Network Considering Magnetizing Impedance’s Frequency Characteristic

Energies, 2017
Signal injection method (SIM) is widely applied to the insulation parameters’ measurement in distribution network for its convenience and safety. It can be divided into two kinds of patterns: injecting a specific frequency signal or several frequencies ...

Pathways and pitfalls: a qualitative study of student experiences in biomedical science education

FEBS Open Bio, EarlyView.
Biomedical science students from underrepresented backgrounds face barriers including financial strain, disrupted laboratory access and cultural exclusion. Peer networks provide vital support when institutional systems are difficult to navigate. To create inclusive learning environments and achieve academic success, educators should blend active, hands‐
