Lightning and lightning protection on distribution systems

Electrical Engineering, 1940
THE CONCEPTIONS of lightning and of lightning discharge currents through arresters have been altered and enlarged by recent studies. Until not long ago the most complete information available on the magnitude and wave shape of lightning surges on electric systems has been that obtained by the cathode-ray oscillograph investigations of lightning ...

LIGHTNING AND LIGHTNING PROTECTION

2004
Lightning is the visible discharge of static electricity within a cloud, betweenclouds, or between the earth and a cloud. It is one of natures most destructive forces.Lightning is the largest single cause of fire in suburban and rural areas, and it killsmore people than tornadoes, hurricanes, and floods combined.

Lightning protection for rotating machines

Electrical Engineering, 1944
The high monetary value and low insulation levels of rotating machines make it necessary to employ special protection. A rotating machine can be conceived as a transmission line with distributed constants, the essential difference being that the machine winding is wound back on itself in the form of turns, which may permit high voltage across the turn ...

Lightning rods that don’t protect

Heart Rhythm, 2015
Is it safe to ablate myocardial tissue with radiofrequency (RF) energy when other metallic objects are near the ablation catheter tip? Will heating occur at objects such as metallic esophageal temperature probes and electrodes on other mapping catheters? Does the presence of nearby metal, such as an implantable cardioverter-defibrillator (ICD) shocking

Development in lightning protection of stations

Electrical Engineering, 1941
THE AIEE transformer sub-committee has recently sponsored a paper1 on the protection of power transformers against lightning surges. The most effective method given combines overhead ground wires, line entrance gaps, and transformer mounted lightning arresters.
