Measurement of degree of non-uniformity of electric field

open access: yesOmsk Scientific Bulletin, 2018
Examination of the degree of non-uniformity of the electromagnetic field assumes the estimate necessary for determining the type of the field and further standard classification, for the purpose of establishing dependencies and determining the applicability of existing and developed sensors in research of parameters of electromagnetic fields.

Grading ring parameters optimization for 220 kV metal‐oxide arrester using 3D‐FEM method and bat algorithm

open access: yesIET Science, Measurement & Technology, 2021
Aging of metal oxide surge arresters is mainly affected by the high electric stress near the high voltage electrode. It has been observed that the distribution of voltage and electric field along an arrester is non‐uniform.

Contribution of a non-uniform magnetic field on the electric power of a photovoltaic panel [PDF]

open access: yes, 2020
Following existing studies on the effects of the uniform magnetic field conducted on a PV module, we note that the effect of a non-uniform magnetic field has not yet been conducted on a PV panel due to its large dimensions. In this paper, the behavior of
