On the basis of an analysis of lightning overvoltages in the circuit of an overhead line and high-voltage underground line, it is shown that, when installing non-linear limiters at the beginning and end of a 100-500 kV underground transmission line, the dimensions of the insulation of such a line of various designs (oil-filled cables, polyethylene-insulated cables, gas-insulated lines) can be chosen...
An engineering method is proposed for determining the characteristics of the electromagnetic field (EMF) along a high-voltage underwater cable. An estimate of the levels of intensity of the magnetic field and longitudinal current density in immediate proximity to 35, 110 and 345 kV underwater cables is given for the purpose of comparison with the levels of threshold values of sensitivity to EMF of...
