Multifunction Transformer Ratio Test Instrument

Feature Highlights

 1、True Three-Phase Testing: Single-Phase Power Input, InternalDigital synthetic three-phase standard sine wave signal generator, through high-fidelity power amplifier,Generate three-phaseTestPower SupplyDistortion less than0.1%Symmetry exceeds0.05%）Output results demonstrate improved equivalence, without the occurrence of misclassification between groups.

 2、Powerful Functionality: Capable of both single-phase measurements and automatic testing of three-phase windings, it can measure polarity and phase angle for both single and three-phase, all in one measurement.AB、BC、CAThe parameters such as the transformer ratio, phase angle, error, tap position, and tap value in three-phase transformers can be automatically identified by group number.

 3Phase Angle Measurement Function: Accurately measures the phase angle between the high and low voltage sides, enabling the measurement of transformer ratio and angle for transformers not at integral points.

 4The Hexagon Diagram Function: Test results are displayed in both numerical and hexagonal vector diagrams, allowing for a clear visualization of the transformer connection group configurations.

 5Blind Test FeatureNo need to select wiring method, no need to select wiring group, measurementY/△、△/YThe transformer does not require external short-circuiting and can automatically switch wiring methods based on the selected test content.Absolutely, the transformer ratio and winding number can be measured on transformers without nameplates.

 6、Tap Changer Testing: Quickly measures the transformer ratio and its error at various tap positions, with the rated transformer ratio inputted only once, eliminating the need for repeated input to calculate the transformer ratio error at each tap position.

 7The product features both turns ratio measurement and operating voltage ratio measurement functions, allowing the operating ratio to more accurately reflect the actual voltage ratio values of the transformer under real operating conditions.

8、Excellent Vibration Resistance: The use of military-grade connectors enhances vibration resistance.

9、 Adopted5.6The inch high-definition true-color LCD screen displays data and vector graphics effects intuitively and finely.

10Our instrument utilizes a digital synthesized standard sine wave as the test source, with distortion less than0.1%Unaffected by the quality of the working power supply.

 11、Convenient to Carry: Compact and lightweight.

 12、Available with an optional high-capacity lithium-ion rechargeable battery, the testing can be conducted on-site without any power source, with a single full charge allowing continuous operation.800Measurements exceeding this level.
