Discharge in Long Air Gaps

2016
Discharge in Long Air Gaps: Modelling and applications presents self-consistent predictive dynamic models of positive and negative discharges in long air gaps. Equivalent models are also derived to predict lightning parameters based on the similarities between long air gap discharges and lightning flashes.

High-Frequency Loss Modeling of Amorphous and Nanocrystalline Cores With Different Air Gaps

IEEE transactions on magnetics, 2022
In general, an air gap plays an important function in the magnetic core. It will enhance the stability of the inductance value of a reactor, increase the power density of the inductor, and optimize the properties of a high-frequency transformer.

Reflective thermal insulation in non-ventilated air-gaps: experimental and theoretical evaluations on the global heat transfer coefficient

, 2021
The refurbishment of existing buildings represents a priority target to reduce global energy consumption. An interesting solution is represented by multilayer systems made by insulating panels mounted on a suitable frame to form non-ventilated air-gaps ...

The Air Gap Sign

Echocardiography, 2014
An elderly female aspirated a donut and subsequently had loss of consciousness and cardiopulmonary arrest. Family members performed chest compressions until emergency medical services arrived and resuscitated the patient with an adequate heart rate and blood pressure.

Numerical modeling of body heat dissipation through static and dynamic clothing air gaps

, 2020
The clothing air gap between the skin surface and clothing layer plays an important role in the body heat dissipation. In this study, we built a numerical model to investigate the heat transfer phenomenon through the clothing air gap in a single layer ...

The impact of air gaps between needle and polymer on electrical treeing in needle-plane samples

IEEE transactions on dielectrics and electrical insulation, 2020
Electrical trees are widely grown in laboratories from metallic needle electrodes to enable the degradation process to proceed rapidly at voltages of ∼10 kV AC.

Discharge of Air Gaps During Ground Potential Live-Line Work on Transmission Lines

, 2020
Ground potential live-line work (GPLW) is a typical type of live-line work on transmission lines. In order to ensure the safety of live-line workers and reduce the consumption of test resources, the discharge of air gaps during GPLW on transmission lines
