Abstract

This study was carried out to investigate the possible risk of magnetic field radiated from the cast resin transformers of electrical service substations rated at 1500 kVA, 11/0.4 kV. The main purposes of this survey is to examine the actual radiated exposure levels for a typical cast resin transformer with current international safety standard and validated them with control environment experimentation in a laboratory. The method used in this study includes comparative analysis of measured data using EMDEX meter with EMCALC software interfaces for data acquisition purposes. Results of three relative measurements were combined in order to associate the radiation effects to the environment. The measurements carried out had involved two separate protocol conditions which are near and far fields. The final results and conclusions showed that there were slight reductions of magnetic fields exposure but not considered to be of great significance since the desired levels should be lowered than 0.4 μT.
