  • Page 6: Introduction

    In addition to measuring a transformer’s turns-ratio, the TRF-100 can also measure a transformer’s excitation current (in milli-amperes) and its winding phase angle. Three test voltages (4 Vac, 40 Vac, 100 Vac) allow the TRF-100 to test CT’s and PT’s, as well as power transformers.
  • Page 7 Test records can be recalled locally or transferred to a PC via the USB interface. Transformer Test Plans The TRF-100 can store up to 128 transformer test-plans in its Flash EEPROM. A test plan is comprised of the transformer nameplate voltages for each tap setting. The calculated turns- ratio based on the nameplate voltages is compared with the measured turns-ratio to derive the percentage error and Pass/Fail results.
