ATRI-3F is Automatic turns ratio instruments mostly uses in Transformer manufacture companies. it display the Ratio between LT and HT windings and also shows its terminal voltage and deviation.
ATRI-3F is Automatic turns ratio instruments mostly uses in Transformer manufacture companies. it display the Ratio between LT and HT windings and also shows its terminal voltage and deviation.
operator easily take testing data record from ATRI-3F using Pen-drive. it saved 32000 data in its internal memory.


Range : 2.00 to 200.0
Accuracy : class 0.1
Application : Ideal for transformer and motor winding ratio measurement.
Auxilliary Power : 230V +/- 20%
Principle : 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 , 100.0Hz, sine wave. Max.500mA
Fully Automated measurement of Turns Ratio,
Excitation current, LT voltage, HT Voltage and polarity
Three Phase Connection enables faster testing
Internal Memory for 500 Transformers tests, Flash Drive Interface for Virtual Unlimited Tests.
Test voltage is applied by 'PUSH to ON' switch, thus allowing safety of personnel during connection/disconnection.
