The personal injury compensation dispute due to the high-voltage electric shock is a kind of new cases accompanied by use of the new energy during the modern society development.

Two-channel high-voltage trigger generator using artificial transmission line as time-delay circuit;

The monitoring of the key parameters in the high-voltage system,responsible for the safe operation of the electric vehicle,including those characterizing the insulation condition of the system,the connection of the power circuit,the performance of the high-voltage contacts,were discussed.

By exploiting the operating principle of the temperature-indicating wax label and image processing technology, a novel method for remote on-line temperature detection of substation high-voltage contacts is put forward.

By analyzing the effects of touch voltage and equipotential bonding on low voltage distribution system,makes clear the importance and necessity of equipotential bonding on design and construction.

To equalize the potential and decrease touch voltage and step voltage on the earth s surface, an optimum design of grounding systems is proposed in this paper.

When the thickness of the low resistivity soil layer increases from the top of the grounding grid to the bottom of the grounding grid, the grounding resistance will increase dramatically and the touch voltage quickly decrease.
