Research on Transformer Winding Deformation and Winding Resistance
DEStech Transactions on Environment, Energy and Earth Science, 2016 In this paper, the influence of transformer winding deformation on the equivalent electrical parameters is studied, and the proximity effect and skin effect caused by AC current in the wire are simulated. It is verified that the current distribution will be affected by the proximity effect and skin effect.

Flat-band assembly for toroidal transformer cores [PDF]
, 1973 Toroidal transformer cores are often banded together by means of strap. Spot welds secure strap. Proper tension is obtained by use of special fixture in conjunction with winding of wire which is placed temporarily on core; winding is excited by dc ...

Sequence determinants of RNA G‐quadruplex unfolding by Arg‐rich regions
FEBS Letters, EarlyView.We show that Arg‐rich peptides selectively unfold RNA G‐quadruplexes, but not RNA stem‐loops or DNA/RNA duplexes. This length‐dependent activity is inhibited by acidic residues and is conserved among SR and SR‐related proteins (SRSF1, SRSF3, SRSF9, U1‐70K, and U2AF1).

Detection of inter turn fault in transformer windings by parameters of their transition processes
Известия высших учебных заведений: Проблемы энергетики, 2019 The proposed method of detection the inter turn fault of transformer windings relates to the area of defectoscopy and allows detecting inter turn faults in a wide range of damaged (closed) turns.

Study on thermal model for calculating transformer hot Spot temperature [PDF]
, 2011 A power transformer is a static piece of apparatus with two or more windings which, by electromagnetic induction, transforms a system of alternating voltage and current into another system of voltage and current usually of different values and at same ...

FEBS Letters, EarlyView.The Ile181Asn variant of human UDP‐xylose synthase (hUXS1), associated with a short‐stature genetic syndrome, has previously been reported as inactive. Our findings demonstrate that Ile181Asn‐hUXS1 retains catalytic activity similar to the wild‐type but exhibits reduced stability, a looser oligomeric state, and an increased tendency to precipitate ...

Iranian Journal of Electrical and Electronic Engineering, 2014 Overvoltage distribution along the transformer winding must be uniform to certify the safety of the operation of the power transformer. Influence of the parameters variation on the impulse voltage distribution (IVD) in disk winding transformer is going ...
