This report was prepared by the Electromagnetics and Novel Applications Laboratory of the University of Cyprus within the framework of measuring and assessing the magnetic field levels by AC power systems at the area of interest:

·         Substation S/S «2262» ‘”PANORAMIC VIEW ATHANASIOU”» in close proximity with house at Potamos Germasoyias, Limassol, on the 29/09/2022 from 10:30 until 11:30.

The measurements were performed according to the measurements of low-frequency magnetic fields with regard to exposure of human beings (IEC 61786:1998) and measurement procedures with regard to public exposure (IEC 62110:2009). More specifically, three-point measurements were performed to assess the fields (assuming non-uniform fields) in the range of 5 Hz – 32 kHz using the EFA-300 Isotropic Field Analyser. The measurements were performed at the position of interest at a height of 1.0 m. above the ground or floor level of the building. It is important to note that in this investigation additional point measurements were taken at locations indicated by the customer (non-standardized measurements outside the measurement procedures with regard to public exposure (IEC 62110:2009).

The recorded measurements were compared to the reference levels described in the Council Recommendation of 12th July 1999 on the limitation of exposure of the general public to electromagnetic fields (0 Hz to 300 GHz), 1999/519/EC. Respect to the recommended reference levels will ensure respect to the basic restrictions. The reference levels of exposure provided in 1999/519/EC are in accordance to the Cypriot Legislation.

The maximum magnetic field values measured at the area of interest are summarized in the following Tables.

Maximum magnetic field values at the area of interest (house in close proximity to the substation).

 

Decision Rule:

·                     From the measurements performed it can be concluded that the magnetic and electric field measurements performed at the position of interest were below the recommended General Public reference levels of the National Exposure Limits provided in 1999/519/EC.
