Underground Power Cables - Anexartisias Street, Geri, Nicosia

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:

·         Underground Power Cables Anexartisias street at Geri, Nicosia, in close proximity to the investigated plot at Geri on the 13/02/2019 from 10:15 am until 11:00 am.

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, the largest electric and magnetic field level is found above conductors. Therefore, the position where the field level is the maximum was found by first measuring at 1.0 m above the ground along the path parallel to the underground line under conductors where possible at appropriate intervals (longitudinal profile), in the range of 5 Hz – 32 kHz using the EFA-300 Isotropic Field Analyser. Then, in order to discover whether anoter peak occurs, measurements were performed at 1.0 m above the ground along the path perpendicular to the overhead line, at the point of the longitudinal profile maximum (lateral profile).

In addition, three-point measurements were performed to assess the fields at the position of interest (assuming non-uniform fields). 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. It is important to note that in this investigation additional point measurements were taken at locations indicated by the customer (nonstandardized 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 12^th 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 and electric field values measured along the underground power lines and at the location of interest are summarized in the following Tables.
