HIGH VOLTAGE LABORATORY
OBJECTIVES AND TASKS
Main tasks of the laboratory are to realize and maintain DC, AC and Impulse high voltage measurement standards at primary level, participate in the intercomparisons to compare its accuracy with other national metrology institutes, disseminate the traceability to the secondary laboratories in Turkey and obtain international traceability of each high voltage measurements made in Turkey .

UME High Voltage Laboratory can realize all AC, DC and Impulse high voltage measurement system calibrations at the laboratory or at the plant system being used. Considering the needs of the country and the industry, special test and measurement system studies and constructions, constituting suitable measurement methods, transfer standard construction designs used for traceability are being made at the laboratory.

Electromechanical industry manufacturers have to test their products according to national, international or military standards. These tests have to be realized in an accredited laboratory that recognized internationally. Standards used in these tests must have international traceability. Additionally, laboratory has performed trainings related to the metrology and special tests on high voltage.
