Electrical Field Distribution and Safety Evaluation of Mobile High Voltage Combined Electrical Equipment

Real Life High Voltage Accident Cases – Teaching Electrical Safety

We discuss the engineering principles of Hi-voltage (any voltage above 600 volts). We cite 4 examples that typify some of the problems facing the Engineer and technician working with Hi-voltages, including geometry considerations, the need to follow proper protocol and the laws (both scientific and political) governing Hi-voltage. Poor design considerations in capacitor construction is the firs...

and could be read with profit by anyone interested in the problem of hydramnios. The Morphologic Manifestations of Uptake of Materials by the Yolk Sac of the Pregnant Rabbit describes how colloidal gold, erythrocytes, cream, and protein, in the form of egg white, are absorbed by the yolk sac. There are several electron microphotographs which are used to illustrate some of the processes. The Dev...

Field distribution of epidural electrical stimulation

Epidural electrical stimulation has been applied in clinics for many years. However, there is still a concern about possible injury to spinal nerves. This study investigated electrical field and current density distribution during direct epidural electrical stimulation. Field distribution models were theoretically deduced, while the distribution of potentials and current were analyzed. The curr...

High-Voltage Electrical Shock Without Injury

A 39-year-old male suffered a minute long shock from a 7200-V power line with no sequelae other than mild quadriceps muscle strain. He had parked a truck next to a highway and was standing on asphalt. He reached into the truck and manipulated a plastic-topped hydraulic lift lever. Suddenly, he could not move or feel. He soon felt a shock and was thrown back. Physical examination was normal exce...
