彩83彩票The ATRT-01 S3 is Vanguard’s fourth generation, micro-processor based, single phase, automatic transformer turns-ratio tester. The ATRT-01 S3 uses the measuring method to determine the transformer turns-ratio. The transformer turns-ratio is determined by precisely measuring the voltages across the unloaded transformer windings. The ATRT-01 S3’s measuring circuitry self adjusts before each measurement to ensure turns-ratio accuracy. Two selectable test voltages, 4Vac and 40Vac, offer flexibility in testing different types of transformers.

  • Standalone or computer-controlled
  • Inexpensive
  • Displays turns-ratio from 0.8-15,000
  • Calculates turns-ratio percentage error
  • Displays winding polarity and phase angle
  • Displays excitation current
