Spectroscopic observation of high breaking capacity fuse arcs

IEE Proceedings - Science, Measurement and Technology, 1994
The complex nature of arcing phenomena In high breaking capacity fuses has made arc modelling and simulation extremely difficult. This paper describes an experimental spectroscopic technique to continuously investigate arc parameters, such as temperature, in this type of fuse. Arc probing was achieved by the use of an optical fibre and the spectroscopy

Long-time operation of high breaking capacity fuses

IEE Proceedings A Science, Measurement and Technology, 1993
The long-time operation of a high breaking capacity fuse using notched strip elements and M-effect alloy, is governed by the interrelationship between the element current distribution, the corresponding element temperature distribution and the M-effect diffusion rate.

Test Circuit for Evaluation of Breaking Capacity of Motor Starters

IEEE Transactions on Industry and General Applications, 1967
Series RL circuits having a power factor between 40 and 50 percent with a resistor shunting the inductor and drawing one percent of the power are presently used for evaluating breaking capacity of motor starters. Transient recovery voltages of these circuits show anomalies which indicate that test circuits in different laboratories may have widely ...

Increasing of operation security and of breaking capacity of surge arresters

2017 IEEE Conference of Russian Young Researchers in Electrical and Electronic Engineering (EIConRus), 2017
Surge arresters with a multi-chamber system that consists of composite electrodes fitted into silicone rubber have been recently proposed for lightning protection of power lines. This article describes experimental and theoretical investigations of the multi-chamber arrester.

Optimal capacity of graded-response perceptrons: a replica-symmetry-breaking solution

Journal of Physics A: Mathematical and General, 1996
Summary: Optimal capacities of perceptrons with graded input-output relations are studied within the first-step replica-symmetry-breaking Gardner approach [\textit{E. Gardner}, ibid. 21, 257 \textit{ff} (1988); Europhys. Lett. 4, 481 \textit{ff} (1988)]. Input-data errors and a limited output precision are allowed.

Breaking into the Cellulosic Ethanol Market: Capacity and Storage Strategies

2010
This paper examines the possibilities of breaking into the cellulosic ethanol market in south Louisiana via strategic feedstock choices and the leveraging of the area’s competitive advantages. A small plant strategy is devised whereby the first-mover problem might be solved, and several scenarios are tested using Net Present Value analysis.

Breaking Capacity of Disconnectors and Earthing Switches Operated in Alternative Gases

2018 IEEE International Conference on High Voltage Engineering and Application (ICHVE), 2018
Due to the ever increasing awareness of environmental concerns, the use of SF 6 in high voltage switchgear technology shall be reduced. One possible approach is the use of alternative insulating gases having different properties than SF 6 , which may require different switchgear design.The focus of this work lies on the breaking capacity of ...

Design and verification of a simulation model for fuses with high-breaking capacity

2009 IEEE Energy Conversion Congress and Exposition, 2009
This paper presents a new simulation model for fuses with high-breaking capacity. Especially when investigating protection concepts for high-power converters, fuse behavior is of major interest. Design basics and applications of modern fuses will be presented, followed by a detailed description of the modeling concept.

Study on Sediment Carrying Capacity of Breaking Wave in Muddy Coast

2019
The muddy coast is an important part of the sea coast of China’s mainland. The muddy plain coast have smaller bank slope, the breaking wave strengthens turbulence of water near the bottom of sea bed during the stormy. Sediment incipience and suspension become easier. Thus high sediment concentration is formed.
