Product Description REXON Fast Transformer Turns Ratio Test Kit Automatic TTR Tester with Stable and Reliable Test DataThe REXON HYG-II Fast Transformer Turns Ratio Test Kit is an automatic TTR tester designed for efficiency and accuracy. With advanced circuits and intelligent control, it delivers fast test results while ensuring stable and reliable data. The instrument is capable of detecting subtle deviations in winding ratios, connection errors, and tap changer defects, helping engineers identify potential transformer problems early. Its robust design ensures consistent performance in factory, laboratory, and field environments. By combining speed with precision, the HYG-II minimizes downtime, reduces testing effort, and guarantees that transformers operate safely and efficiently in demanding applications.PrefaceAccording to the IEC and the relevant national standards, in power transformer production, the user acceptance and maintenance test process, the transformer ratio test is to do projects, it can effectively monitor the transformer products manufactured and used in the process of quality, prevent the transformer interturn short circuit, open circuit, connection error, voltage regulating switch internal fault or contact fault. For my company to develop and produce the Transformer Ratio Tester HYG-II on the original basis according to the user's requirements of the site use, make the operation more convenient, complete functions, stable and reliable data, and test speed. Adapting to various small, medium and large transformer ratio tests is needed.Product DescriptionApplicationThe REXON HYG-II is a high-precision digital transformer turns ratio (TTR) tester used to measure the voltage ratio and phase displacement of transformer windings. It is an essential diagnostic tool in power systems, transformer manufacturing, and maintenance operations.1. Power System Operation and MaintenanceApplications: Substation power transformers, voltage transformers (VTs), and instrument transformersPurpose: Routine testing to detect abnormalities in winding ratio due to shorted turns or connection faultsBenefits: Enhances grid reliability and prevents unplanned outages 2. Transformer Manufacturing and Factory TestingApplications: Distribution transformers, power transformers, special-purpose transformersPurpose: Verify that the actual turns ratio matches the design specifications during productionBenefits: Ensures product quality and compliance with IEC or ANSI standards3. Commissioning and Installation VerificationApplications: New substations, transformer replacement projects, or system upgradesPurpose: Confirm correct tap position, winding polarity, and phase group before energizingBenefits: Prevents costly errors due to incorrect wiring or connection mistakes4. High-Voltage Testing and Type TestingApplications: Testing labs, utilities, or inspection authoritiesPurpose: Used in conjunction with insulation resistance, winding resistance, and other tests to assess transformer performanceBenefits: Part of routine type tests, FAT (Factory Acceptance Test), and SAT (Site Acceptance Test)5. Fault Diagnosis and Preventive MaintenanceApplications: Transformers suspected of damage after faults, overloads, or agingPurpose: Detect shorted or open windings, tap changer malfunctions, or phase mismatchesBenefits: Aids in root cause analysis and ensures safe continued operationSuitable for a Wide Range of EquipmentOil-immersed transformersDry-type transformersAutotransformersPhase-shifting transformersVoltage transformers (VTs) and instrument transformersThe REXON HYG-II supports automated measurement, digital display, and data storage functions, making it ideal for field testing, commissioning, and laboratory analysis. Its accuracy and ease of use make it a reliable tool for utilities, OEMs, and testing service providers. Characteristics 1. The English and Chinese menu prompts, the operation is simple and convenient.2. Ratio measurement range is large: 1-100003.
