Low Pressure Arc Characteristics
Physics, 1936The results of an oscillographic study of the short a.c. arc between pure graphite electrodes show that the reignition potential is a linear function of the gas pressure for air, N2, O2, and CO2. The relation is expressed by Vr=A+Bp. The constant A follows the minimum sparking potential of the gas, increases with the rate of rise of the impressed ...

The ARC-HPF with independent trimming of the main characteristics
2017 24th IEEE International Conference on Electronics, Circuits and Systems (ICECS), 2017A new structure of the active RC highpass filter (HPF) is proposed. It is shown that in the HPF under consideration an independent trimming of the main characteristics, such as a pole frequency, a pole attenuation, and a transfer ratio in the bandwidth, is provided. This scheme is recommended as a second-order link in more complicated HPF.

THE WELDING ARC STATIC CHARACTERISTIC
2023Труби для газо- і нафтопровідних магістралей експлуатуються при високих тисках і низьких температурах, тому виготовляються з високоміцних сталей, при зварюванні яких трудно забезпечити ударну в’язкість зварних з’єднань. При електродуговому зварюванні труб значно зростає магнітне поле зварювального струму, магнітне дуття, електромагнітна сила відхиляє ...

2017 4th International Conference on Electric Power Equipment - Switching Technology (ICEPE-ST), 2017
The paper investigates the pulsed AMF arc control on the vacuum arc and the post arc characteristic to reveal the mechanism of AMF arc control in different control time and find the proper AMF arc control. The pulsed AMF control system is designed and the pulse width is adjusting from 1.5ms to 10ms.

Characteristics of the molybdenum-depositing arc and the metal-arc melting process
Proceedings of the IEE Part A: Power Engineering, 1955The arc melting of metals such as molybdenum, using the consumable-electrode process, is described. After a discussion of the nature, the shape and the stability of the arc, consideration is given to its behaviour inside a water-cooled copper mould when using a.c. and d.c. power supplies both under vacuum and in an argon atmosphere.

Arc Voltage Characteristics of Medium-Low Voltage Arc Fault in Short Gaps
2018 IEEE Industry Applications Society Annual Meeting (IAS), 2018With the increasing interconnected distribution level power systems, the risks of low voltage arc flash draw more attentions. Arc voltage, as the critical factor in arc flash mitigation, is able to determine the insulation distance and re-striking voltage level. However, unlike to high voltage long arc, the medium-low voltage short shows a more dynamic
