1. Physiological effects of electromagnetic fields

-knowledge of health problems

-assess the impact of radiation

-organizations within the electromagnetic field evolution

-tissue-damaging effect

-body part- different value

2. Defense

-levels, knowledge of international standards


-electric-field strength


-values at work

-compliance with the recommended clearances for knowledge

-voltage level

-magnetic-induction values

-electric-field strength values

3. Instruments for knowledge

-Emdex, Linda, Emcalc, EB2005

4. Lines near the magnetic induction measured

-high-voltage transmission lines (120 kV, 220 kV, 400 kV)

-representation of the values measured by the distance

3D-representation of the values measured by image-distance


-substation measurements,

5. Magnetic induction and electric field simulation


-Phase-managers indicated

- Determination of sagging

-load-current values, the computation-

-current-voltage values and calculation

- spatial distribution of the various leaders

-statement of values-table

6. Interpretation of measurement results

-below the limit values

-much smaller than the values for magnetic and electric field
