Estimation of the electromagnetic field exposure during LLW on a HV tower with cable heads

The paper deals with the numerical estimation of the electromagnetic field exposure during live-line working (LLW) on a terminal tower of a 110 kV line. The above tower is equipped with cable heads, lightning arresters and vertical cabling. This vertical cabling connects the overhead HV line with underground one. Distributions of the electric and magnetic fields in the LLW zones as well as the electric field (eddy currents) induced in the worker's organism are computed with an author's own software package. This software is based on a numerical technique that combines the boundary element and charge simulation methods. Presented computational results are related to the current European and Polish regulations regarding the workers' exposure to the electromagnetic fields.
