Electric and magnetic field measurements in a high voltage center

This paper investigates the electric and magnetic fields inside a high voltage center in Philippi, Greece, constituted both of 400/150 kV and 150/20 kV substation areas. Results of previous field measurements and calculations in substations are presented first. The basic data distinguishing the examined center from previously examined substations follow. The main results of the field measurements in the areas of the above mentioned center are presented in relevant diagrams. Conclusions arising from the comparison of the measured field values with relevant reference levels in force for safe general public and occupational exposure as well as with the results of previous research are finally given.
