“…It has been observed in the literature that bubble nucleation at the surface of a cathode grid lowers the onset of electric discharge [62,63]. In order to test whether quenching bubble formation at the wires would allow higher voltage levels without light discharge, a bubble-quenching test was performed by introducing a 5 K temperature gradient in detector.…”

A workshop was held at Fermilab November 8-9, 2013 to discuss the challenges of using high voltage in noble liquids. The participants spanned the fields of neutrino, dark matter, and electric dipole moment physics. All presentations at the workshop were made in plenary sessions. This document summarizes the experiences and lessons learned from experiments in these fields at developing high voltage systems in noble liquids.

“…To study streamer growth without causing a total discharge two routes have been pursued in the literature. Firstly a transient voltage impulse can be applied to the sample, several works have been published taking this approach [3][4][5]. For study of partial breakdown under ac voltage a composite system is preferred.…”

Abstract:Interest in superconductors for use in the transmission and distribution of power has grown since the advent of High Temperature Superconductors (HTS). The benefits of reduced ohmic losses leading to greater operational efficiency appear attractive to power transmission and distribution companies. Potentially this technology will increase power transfer for the same or lower voltage and for the same or smaller physical dimensions. For the successful employment of this technology in the field, power utilities must be convinced of the operational reliability of designs. Many of these designs make use of liquid nitrogen as the system coolant and also as a dielectric fluid. It is therefore vital that liquid nitrogen be well characterised as a dielectric medium. This paper describes an experiment to characterise partial discharge behaviour in a non-uniform field geometry. A technique is described which allows synchronised capture and measurement of apparent charge and images of density change streamer activity. ϕ q n analysis of ac results has been completed and characterisation of partial discharge behaviour is presented and discussed.
