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

·         Substation Old Station (Παλαιό Μηχανοστάσιο) and office at Nikiforou Foka Street Limassol on the 14/05/2018 from 12:00 pm until 12:40 pm.

The measurements were performed according to the measurements of low-frequency magnetic and electric 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 three heights 0.5 m, 1.0 m and 1.5 m. above the ground or floor level of the building. Beside power equipment or in a building, measurement was performed at a horizontal distance of 0.2 m and 2.0 m from its surface or boundary wall.

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 location of interest are summarized in the following Tables.
