Design of an Anti-Corona Device for HVAC Substation Connectors

open access: yesEnergies, 2022
One of the aspects to consider during high-voltage (HV) equipment design is the reduction in the probability of corona effect onset. Indeed, the corona effect is related to high electric field values beyond the equipment’s insulation levels and ...

Design and implementation of a small AODF

open access: yesThe Journal of Engineering, 2019
Cross-connection is the only point in the communications field that has not been automated. With the many fibre networks that have been built, there is strong demand from operators for an automatic optical distribution frame (AODF) to reduce operational ...

Study on influence factors and restraining measures of composite insulator end heating caused by housing microstructure defects

open access: yesIET Science, Measurement & Technology, 2021
In recent years, the quantity and proportion of heating defects have increased significantly with more composite insulators used in transmission lines and deterioration of early composite insulators. End heating is the main characteristic of this kind of

Electrically packaged silicon-organic hybrid (SOH) I/Q-modulator for 64 GBd operation [PDF]

open access: yes, 2019
Silicon-organic hybrid (SOH) electro-optic (EO) modulators combine small footprint with low operating voltage and hence low power dissipation, thus lending themselves to on-chip integration of large-scale device arrays.
