EFFICIENCY STANDARD OF DISTRIBUTION TRANSFORMERS IN IRAN

In this paper, values for determining the minimum standard criteria for energy efficiency transformers for distribution transformers up to 25 kVA 2500 to exploit the three-phase distribution network, with natural cooling to work in closed or open space, with the frequency of HZ 50 offers. Due to the equipment in accordance with national standards laboratories country is Iran, and Since this standard is derived from IEC standards and compliance with standard efficiency transformer CENELEC standard IEC, CENELEC standard based on transformer efficiency standards have been distributed. Transformers according to CENELEC standard mortality sterility (3 patterns) and pregnancy (3mode) to 9 modes are divided. Considering the technical facilities of the country's fifth confirmed case has been finally proposed efficiency standard for Iran has been proposed.
