The Electric Strength of Air-III
Transactions of the American Institute of Electrical Engineers, 1911The two earlier papers of this series discussed more particularly the conditions governing the start of the high voltage corona. This line of investigation is continued to some extent in the present paper. In addition some interesting observations of the properties of the full-formed corona itself are recorded.

The electric strength of copolymers
Journal of Materials Science, 1977Careful measurements of the electric strength of styrene—butadiene copolymers together with their parent homopolymers over a wide range of temperature are presented. The marked reduction of strength characteristic of a non-polar amorphous material occurs at a temperature indistinguishable from the glass transition temperature determined by differential

Air is the commonest and most widely used of insulators. Its insulating characteristics are remarkably good; it has low specific inductive capacity, very low conductivity, and an electric strength or resistance to rupture which until recently has met all the demands of the electrical engineer.

PERCUTANEOUS ELECTRICAL STIMULATION IN STRENGTH TRAINING
Journal of Strength and Conditioning Research, 2005Numerous studies have used percutaneous electrical stimulation (PES) in the context of training programs to develop strength and physical performance in healthy populations (sedentary or trained). Significant increases in muscle and fiber cross-sectional area, isokinetic peak torque, maximal isometric and dynamic strength, and motor performance skills ...

In the theory of electric strength, usually referred to as free-volume theory, breakdown is initiated by free electrons accelerated by electric field in the largest of the holes present in the amorphous phase of all polymers. In contrast to previous publications, the breakdown is treated as the final stage of the disproportionate rise of the electron ...

The electric strength of fibrous glass
Electrical Engineering, 1939The ideal, and probably future, use of fibrous glass for electrical insulation is without an organic filler. Therefore, it is important first to know its electric strength in unimpregnated condition. Test results show its high qualities at elevated gas pressures and temperatures.

Nonsustained Breakdowns in Electrical Strength Tests
IEEE Transactions on Power Apparatus and Systems, 1966A study of nonsustained breakdowns has been made during alternating voltage tests on the electric strength of various commercial insulants in transformer oil and compressed sulphur hexafluoride and nitrogen. Such breakdowns do not cause sustained arcing and current flow.

Electric strength of transformer insulation
Proceedings of the Institution of Electrical Engineers, 1969High-voltage power transformers incorporate large quantities of insulation which is easily contaminated, and the dielectric strength is, in consequence, uncertain. This paper reports the results of electric-strength tests on transformer oil, alone and in combination with solid insulation, under various conditions.

The electric strength of hydrocarbon gases
British Journal of Applied Physics, 1956Careful measurements of the static electric strengths of a number of pure hydrocarbon gases over a range of pressure and spark-gap spacings, including the Paschen minimum are reported. A relationship between strength and molecular structure is found which, if unsaturated compounds such as ethylene, acetylene and butadiene are included, is not so simple
