The 1st overhead power line Vasilikos1 - Polemidhia1 is of rated voltage of 132 kV and rated maximum nominal power of 150 MVA. At the time when the measurements were performed, the load of the overhead power line was 38.43 MVA. The Resultant Load of all three phases for the Vasilikos1 - Polemidhia1 was 25.62 % utilisation of the nominal load power.
The 2nd overhead power line Vasilikos2 - Polemidhia2 is of rated voltage of 132 kV and rated maximum nominal power of 150 MVA. At the time when the measurements were performed, the load of the overhead power line was 38.35 MVA. The Resultant Load of all three phases for the Vasilikos2 - Polemidhia2 was 25.57 % utilisation of the nominal load power.
The highest magnetic field measurement was observed along the overhead power lines, with a value 0.302 μT (3 m away from the starting point, at 1.75 m height) and a percent- age of 0.302 % as compared to the ICNIRP General Public standard. Accordingly a detailed description of the maximum measured magnetic elds in the area under investigation is shown in the table below.
The following table summarizes the magnetic field measurements taken in the area under investigation.
