Transformer Ratio Comprehensive Tester

ED0203BThe Transformer Ratio Group Test Set, also known as the Transformer Transformer Ratio Group Test Set, is an ideal testing instrument for power system, transformer manufacturers, and railway electrical systems to perform transformer ratio tests, group tests, polarity tests, and angle tests. This transformer ratio group test set automatically generates a stable amplitude and constant phase three-phase, two-phase, or single-phase standard power supply.

ED0203BThe Transformer Ratio and Group Test Instrument is an ideal testing device for power systems, transformer manufacturers, and railway electrical systems to conduct transformer ratio, group, polarity, and angle tests. This transformer ratio and group test instrument automatically generates a stable amplitude and constant phase three-phase, two-phase, or single-phase standard power supply.ED0203BTransformer Ratio Group Tester is suitable for the testing of three-phase transformers in the power system.ZScott-type, inverse Scott, and balanced transformers for transformer windings, rectifier transformers, and railway electrical systems can accurately measure the transformation ratio and errors.ED0203BThe Transformer Ratio Group Test Instrument features a large LCD screen, full Chinese menu, and Chinese character print output. It is well-equipped with comprehensive functions and easy-to-use operation, making it an ideal testing instrument for power systems, transformer manufacturers, and railway electrical systems to conduct transformer ratio, group, polarity, and phase difference tests.

 ED0203BThe Transformer Ratio Group Test Instrument is powered by a single-phase power supply, internally using an amplification power module to generate a three-phase power supply output to the high voltage side of the transformer. The low voltage side performs sampling, which is then processed and displayed on the main unit. It can conduct tests on the ratio, error, group, or phase angle of conventional three-phase transformers or other special transformers. Additionally, this test instrument provides a set of phase difference tests.90The dual-phase power supply output is capable of testing the voltage ratio and phase difference of inverse Scott transformers, widely used in intelligent substation for new power equipment.
