This report was prepared by the
Electromagnetics and Novel Applications Laboratory (Electromagnetics and Novel
Applications Lab) 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 “Poor Families B” and
residence at 37 Spyrou Kyprianou
str., Sotera, Famagusta from 08:45 am until 09:45 am.
The
measurements were performed according to the measurement procedures with regard
to public exposure (IEC 62110:2009 [1]). 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 m and 1.5 m. above the ground or floor level of the building. Beside power
equipment or in a building, measurements were performed at a horizontal
distance of 0.2 m and 2 m from the 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 [2]. Respect to of all recommended
reference levels will ensure respect of basic restrictions. The reference
levels of exposure
provided in 1999/519/EC are in accordance to the Cypriot Legislation.
The electric and magnetic field measurements
performed at the position of interest were below the recommended reference
levels of exposure provided in 1999/519/EC.
The highest magnetic field values measured at the location of interest
are summarized in the following Tables.
