Three Phase Automatic Turns Ratio Instrument

Three Phase Automatic Turns Ratio Instrument

  • Model: ATRI-3
  • Range: 2.00 to 200.0
  • Accuracy : class 0.1
  • Ideal for tranformer and motor winding ratio measurement
  • Auxilliary Power: 230V +/- 20%
  • Measures and displays Transformer Turns Ratio by using voltage ratio method.
  • Applying Test Voltage to the Low Voltage winding of a transformer and accurately measures
  • the resulting voltage from the High Voltage winding. As per ANSI/IEEE C57.12.90
  • Standard Accessories: 10 meter long wire for three phase connection on LT and HT sides.
  • Dimension: 131(H) by 280(W) by 230(depth)
  • Excitation : 1.8V , 150.0Hz, sine wave. Max.500mA
  • Fully Automated measurement of Turns Ratio, Excitation current, LT voltage, HT Voltage and polarity
  • Three Phase Connection enables faster testing
  • Test voltage is applied by 'PUSH to ON' switch, thus allowing safety of personnel during connection/disconnection
  • (Optional) Data can be saved in memory card

Features

  • Automatic Turns ratio Meter
  • Powered by Auxilliary power supply at nominal 230V.
  • Ideal for Testing Distribution and Power Transformers
  • Works for ratios from 5.00 to 200.0
  • Following Parameters can be observed:
  • Turns Ratio value
  • LT Side Voltage
  • LT Side Current
  • HT Side voltage
  • Mode changes from Y-Y to D-Y
  • User can connect Three Phase wires at one time, and then turn knob to check turns ratio for each
  • phase separately
  • Accuracy: 0.1 class
