Introduction Overvoltages Causes and effects Indirect effects of lightning strokes Users of telephone, telematics* and IT systems are not only faced with decreasing reliability, limited operating safety and declining operational availability of these systems, but more and more frequently also with the problem of overvoltages. The two main reasons for this are: - The use of microchip has increased the susceptance to failure, and every year, the number of component parts in microchips goes up at the expense of insulation. Due to the very small insulation distances (µ magnitude), even a minor...

Introduction Overvoltages Electrostatic overvoltages Effects of overvoltage that can occur with all four kinds described: Electrostatic discharges are caused by human beings. Human beings have an electrical capacity of 100-300 pf. Walking on carpets with synthetic fiber, they can become charged up to 15 kV and discharge in a few nanoseconds with a current of about 10 Ampere. In particular, highly integrated electronic systems (CMOS...) are very susceptible to this kind of disturbances. Their effect can be a complete destruction of the circuits. - destruction - flashover in semiconductor...
