Automatic Three Phase Transformer Turns Ratio Meter

Specifications and Product Details:

Range: 3.00 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

Automatic Turns ratio Meter
Powered by Auxilliary power supply at nominal 230V.
Ideal for Testing Distribution and Power Transformers
