35. 60 Hz turns ratio tester without a built in thermal printer The general term ATRT 03 or ATRT is used in this manual to refer to any of the ATRT 03 models Any differences are clearly described where applicable The ATRT 03 determines the transformer turns ratio using the IEEE C57 12 90 measurement method The transformer turns ratio ranging from 0 8 to 15 000 is determined by precisely measuring the voltages across the unloaded transformer windings To ensure accuracy the ATRT 03 s measuring circuitry self calibrates before each measurement It requires neither adjustment nor temperature compensation The ATRT 03 s turns ratio measurement accuracy is 0 196 or better The ATRT 03 can perform a specific test for each transformer type such as single phase delta to Y Y to delta delta to delta or Y to Y without the need to switch test hookup cables Also the unit s automatic transformer phase detection feature can detect different transformer vector diagrams The ATRT 03 can automatically detect and test 67 transformer types defined by ANSI CEI IEC and Australian standards Transformer Test Voltage To prevent an accidental wrong test lead hook up e g when the operator reverses H and X leads the ATRT 03 outputs a low level test voltage to verify the hook up condition before applying the full test voltage to the transformer Three test voltages 8 Vac 40 Vac 100 Vac allow the ATRT 03 to test CT s and PT s as well as power transfo
