High Voltage, EarlyView.ABSTRACT The breathing system of an oil‐immersed transformer is of vital importance for maintaining equilibrium between internal and external pressures, with any malfunction potentially disrupting the transformer's stable operation. This study develops a thermal–fluid–structure interaction (TFSI) model to simulate the breathing phenomenon in a 110 kV ...

The Analogia Entis for Reformed Theology: Retrieving Calvin's Implicit Metaphysics
Modern Theology, EarlyView.Abstract The famous controversy between Emil Brunner and Karl Barth which led to Barth's ‘No!’ was driven by disagreements over how to read John Calvin: Barth and Brunner never agreed on whether Calvin had a doctrine of the analogy of being. This article rekindles the debate.

Известия высших учебных заведений и энергетических объединенний СНГ: Энергетика, 2017 Principles of implementation of current protection of elements of electric power systems with power transformers are considered. In some cases, in facilities with power transformers there could be an inrush of a magnetizing current that can cause a false

Controlled transition full-bridge hybrid multilevel converter with chain-links of full-bridge cells [PDF]
, 2016 This paper proposes a controlled transition full-bridge (CTFB) hybrid multilevel converter (HMC) for medium and high voltage applications. It employs a full-bridge cell chain-link (FB-CL) between the two legs in each phase to generate multilevel bipolar ...

A Forced Union: Exploring the Consequences of India's Removal of Jammu and Kashmir's Special Status
Nations and Nationalism, EarlyView.ABSTRACT This article adds to academic literature interested in two core questions: What happens to residents as a result of an annexation? And how do aggressor states maintain control over an annexed territory where there is a history of insurgency and mobilization for independence?

Research on Inrush Current Suppression of Transformer Based on Changeable Closing Angle
Zhongguo dianli, 2022 The transformer no-load closing inrush current may cause safety problems in power grid, and the controlled switching technology with fixed target angle still has room for improvement in suppressing inrush current. A transformer inrush current suppression

Rectification Free from Inrush Current
IEEJ Transactions on Industry Applications, 2002 A simple stopper of inrush current, with TRIAC, is proposed for rectification systems. Among all the switching devices only TRIAC has reverse trigger-mode that enables direct triggering by the voltage of capacitor, only after its charging up through a resistor.
