Dielectric breakdown of sulphur hexafluoride
C. N. Works,T. W. Dakin +1 more
TL;DR: In this paper, the authors present some anomalies in the dielectric breakdown of sulphur hexafluoride as functions of pressure and electrode separation in a nonuniform field.

Corona discharges in d-c and partially rectified a-c insulation systems
TL;DR: In this article, the authors investigated the effect of partial corona discharges on a-c insulation systems and found that the rate of erosion or penetration of insulation barriers is correspondingly reduced, and it has been practical to apply much higher d-c stresses, without completely preventing corona, than with a -c cases.

The high temperature dielectric properties of reconstituted micas
TL;DR: In this article, an investigation was initiated to determine the possible improvement in high temperature dielectric properties of reconstituted mica which might be achieved by purification and modification techniques.
Instrumentation and measurements
TL;DR: The calibration of capacitors at the National Physical Laboratory in Britain is discussed in a paper by Rayner and Ford as mentioned in this paper, where they measured the effect of humidity on the capacitance end power factor of precision air capacitors and notes that changes in capacitance of 3 in 10,000 are noted at relative humidity of 65%.

Microwave Dielectric Measurements
T. W. Dakin,C. N. Works +1 more
TL;DR: In this paper, the dielectric properties of some common plastic and ceramic materials at 10 cm and 3 cm wave lengths were measured using a short circuited end of the transmission line, and the properties of the sample, calculated from the position of a minimum of the standing wave and the ratio of the minimum field strength to the maximum field strength, were given.

A Capacitance Bridge Method for Measuring Integrated Corona-Charge Transfer and Power Loss per Cycle
Thomas W. Dakin,P. J. Malinaric +1 more
TL;DR: In this paper, a more sensitive and accurate circuit has been devised and tested for showing integrated corona charge transfer per cycle in insulation samples, which can be used as a very accurate and more rapid quality-control measurement of degree of impregnation or residual voids in apparatus insulation.

The voltage endurance of cast epoxy resin-II
S. A. Studniarz,Thomas W. Dakin +1 more
TL;DR: In this paper, the authors summarized the progress of an extensive study of the ac voltage endurance, extending from a single cycle to more than a year, for cast silica-filled epoxy resin, with recessed silver paint electrodes and cast-in aluminum electrodes, giving a nearly uniform electric field.
