N.RasolZ. 62011116This study investigated the magnetic field survey of two electric power substations with power capacity of 1500 kVA, 11/0.4 kV which resided in a typical high rise office building in Kuala Lumpur, Malaysia. The purpose of a survey is to examine the exposure levels of magnetic radiation from its electric substation. The method used in this study includes comparative analysis of measured data using EMDEX meter and interfaces with EMCALC software for linear data acquisition. Results of two substations, which located in the basement floor and 15th floors were obtained throughout normal working hours. The measurements were arranged by applying two separate protocol conditions which is near and far fields. The specifications of measuring instruments used in this assessment were also displayed. Final conclusions were made based on the reduction rate calculation as an indicator values to determine the safety levels and comparison to the international standard guidelines.]]>Ahlbom, A., N.
