A Study of Electric Breakdown Theory to Model Dielectric Surface Flashover
Electric flashover on power system apparatus and safety equipment can result in destruction to equipment and injury to workers, as well as pose a danger to anyone in the vicinity of this occurring. This phenomenon still continues to be an issue today despite over 100 years of research into the problem. It was determined that an exhaustive literature review should be performed to investigate mat...

متن کاملInitiation Mechanism of Pulsed Surface Flashover along Silicon in Vacuum by Pre-breakdown Conduction and Photon Emission
Pre-breakdown (leakage) and breakdown currents and photon-emission associated with the currents, under impulse (0.36!10 IJ-S) voltage stress, along high purity (p>30 KQ em) silicon, with and without gold end contacts in vacuum (-lQ-6 Torr), are discussed. Three distinct phases leading to the breakdown condition are observed. These are one-carrier (hole) leakage current, two-carrier (electrons a...
متن کاملInvestigation of Long-Term Thermal Insulation Performance of Vacuum Insulation Panels with Various Enveloping Methods
To practically apply vacuum insulation panels (VIPs) to buildings or home appliances, VIPs have demanded long-term lifespan with outstanding insulation performance. Service lives of VIPs enveloped with Al-foil and three-layer Al-metallized envelope are calculated. For Al-foil envelope, the service life is longer but edge conduction is too large compared with the Al-metallized envelope. To incre...
متن کاملStatistical Evaluation of Critical Flashover and Withstand Voltage for Small Airgap
Insulation co-ordination and the risk of failure for insulation can be predicted if critical flashover (CFO) and insulation withstand voltages are known. The paper aims at using the statistical method of evaluating the critical flashover and the withstand voltage for an airgap distance of 10cm. The work was carried out with a point-plane electrode (needle point) arrangement using air as the die...
