HZTTR80A Transformer Turns Ratio Tester Fast delivery I 24-hour customer service I customizable Product Introduction The HZTTR80A transformer ratio test device is a fully automatic tester. It integrates the testing functions of turn ratio, voltage ratio, vector relationship, winding connection, polarity, tap position, and excitation current. This tester is a lightweight and portable instrument, with both the tester and its accessories housed in a multi-functional engineering plastic case that is resistant to cold, heat, sealing, waterproof, and shockproof, making it convenient for field tests. This test device can be used to test single-phase and three-phase transformers, both with and without taps. The instrument can be controlled throughout using a dedicated APP downloaded on an Android phone or tablet, allowing for the storage and upload of test data for easy review. Test Range:Transformation Ratio -- 0.9 to 10000, Current -- 0 to 2000mA, Angle -- 0 to 360° Resolution:Ratio -- Minimum 0.0001, Current -- 0.001 mA, Angl^^QJ^ Test Voltage:AC 5V @ 1 A, AC 80V @ 80mA Operating Power Supply:The maximum power is 50W Ambient Temperature: -10°C to 40°C Relative Humidity:<85%, non-condensing Dimensions:Main Unit: 360x290x170(mm) •Equipped with blind test function to accurately measure the transformer's ratio and connection group when the connection group of a three-phase transformer is unknown. •Capable of testing autotransformers, Z-type transformers, and phase-shifting transformers. •Added tap mode settings to accommodate transformers with high voltage at high tap positions and low voltage at high tap positions. •Added low-voltage side tap settings to accommodate transformers with taps on the low-voltage side. •Graphical display settings for more intuitive readings. •Simultaneous measurement of three-phase ratios during three-phase transformer testing for faster testing speed.
