5.5 Insulation and Dielectric Breakdown III
- Jacob Stephens (MIT)
Insulation between high voltage electrodes is often in the form of micro-gaps which leverage the high breakdown voltage that occurs on the near-side of Paschen’s curve. Structures on the electrodes are a concern due to electric field enhancement that can occur. The breakdown voltage in atmospheric pressure micro-gaps having multiple cathode field emitters was computationally investigated using...
Microscale gas breakdown plays a critical role in microplasma generation for numerous applications and device lifetime for miniaturized electronics. This work provides further insight into the spatio-temporal dynamics of pulsed gas breakdown for different gap distances using an in-situ electrical-optical measurement method. Time-resolved sequential images and the corresponding photon number ...
Nanosecond repetitively pulsed discharge (NRPD) is attracting extensive attention recently due to its unique chemistry and physics properties, which are important for various applications including the plasma fruit sterilization. Streamer dynamics and discharge mode transition were fundamental properties of NRPD. Previous studies mainly investigated the NRPD by using two consecutive pulses and...
Unlike pure water, electrical breakdown in seawater has not been studied broadly, in seawater the ions are provided by the salt content leading to a conductivity of about 53mS/cm in contrast, purified water has a theoretical conductivity of 55nS/cm, when short pulses are applied the contribution of the ions to current conduction is weakened due to the low drift velocity of the ions and...

Polycarbonate dielectrics like Lexan and polyetherimides such as Ultem have long been used as dielectrics in Marx generators, Blumlein lines, and in other pulsed...
I.INTRODUCTION
During the long-term running of transformer, its oil-paper insulation system withstands various stresses of temperature, mechanical stresses and electric fields, which will continue to age. There is much research on electrical aging and heat aging, but few research on aging under mechanical stress.
II.EXPERIMENTAL PLATFORM AND PROCESS
In order to simulate the pressing...
