Prediction and Analysis of Transient Electric Field in DC Yard of Flexible Converter Station Under Short-Circuit Conditions

open access: yesZhongguo dianli, 2021
In the case of short-circuit fault, the flexible DC converter station would produce transient yet strong electromagnetic field, which would impact on the secondary equipment in the converter station.

Measuring circuits of two double electro-induction spherical sensors of electric field strength of closed type constructively united into a single whole [PDF]

open access: yesОмский научный вестник, 2022
To control the levels of electric fields, electric field strength sensors are required. Currently, for these purposes, the most promising are dual electric induction sensors, which are a constructive combination of two double sensors into one whole ...

Effect of electroosmotic flow on brine imbibition in porous media

open access: yesWater Science and Engineering, 2009
Based on Darcy's Law and the Helmholta-Smoluchowski equation, an imbibition velocity formula for the water phase with an electric field was deduced, showing that the imbibition velocity with an electric field is to various extents not only related to the

Consistency Restrictions on Maximal Electric-Field Strength in Quantum Field Theory [PDF]

open access: yesPhysical Review Letters, 2008
Quantum field theory with an external background can be considered as a consistent model only if backreaction is relatively small with respect to the background. To find the corresponding consistency restrictions on an external electric field and its duration in QED and QCD, we analyze the mean-energy density of quantized fields for an arbitrary ...

Calculation of electric field strengths at a sharp edge [PDF]

open access: yesInternational Journal of Mass Spectrometry and Ion Physics, 1968
Sharp edges were first used for field ionisation mass spectrometry by Beckey. Although Cross and Robertson found that etched metal foils were more effective than razor blades for field ionisation, blades are very convenient for determination of field ionisation mass spectra, as reported by Robertson and Viney.

Electric field mill for the simultaneous measurement of electric field strength and ion current diensity [PDF]

open access: yes, 1995
In the last 20 years, the use of high voltage direct current (HVDC) power transmission has grown considerably. With the increase in the number of HVDC transmission lines and in the transmission voltages, concern has increased as to possible health effects. For research on these health effects to be carried out, it is necessary to measure the electrical

Electric field distribution characteristics of typical insulation structures in aramid–synthetic ester oil transformers [PDF]

open access: yesAIP Advances
Both aramid paper and synthetic ester oil have high heat resistance levels. Using them as the main insulating materials for transformers is expected to improve the heat resistance level of oil-immersed transformers.
