Abstract: In this research, we demonstrate the effect of changing ambient temperature on the intensity of the electromagnetic field generated near high voltage power transmission lines (132 kV) in selected area South of Mosul city (Iraq), by measuring the increase in conductor length between two consecutive towers using electronic total station Leica TPS400 series. In the set of measurement cond uctor length changes from (30-80 cm) and magnetic field intensity changes from (33-44 mG) due to temperature changes range (4-53°C). The calculated magnetic and electric field stages are compared to experience strategies given by International Commission on Non-Ionizing Radiation Protection (ICNIRP) to evaluate the risks. It has been noticed that the higher the ambient temperature around conductor, the more intense electromagnetic field which in turn leads to the lack of safe pasacclimatee this at constant load. As also noted, the less distance between two consecutive towers (SPAN) the greater the acclimate. So, these observations should be taken in account when design power transmissions line in those areas.
