There are significant differences between the comprehensive testing instrument for variable frequency transformers and the general testing instrument in terms of functionality, testing objects, testing accuracy and efficiency, portability, and application scenarios
1. Functional differences:
① The comprehensive tester for variable frequency transformers is a multifunctional testing equipment designed specifically for transformers. It can complete tasks such as volt ampere characteristics, transformation ratio, polarity, error curve, angle difference ratio difference, calculation of inflection point, and secondary side circuit inspection. It supports the detection of steady-state and instantaneous parameters of CT and PT.
② The universal tester has a wide range of functions, including detecting various values such as capacitance, resistance, voltage, current, power, as well as quantifying circuit parameters such as excitation parameters and functional parameters. However, its specific testing functions for transformers are relatively limited.
2. Test object:
① The comprehensive tester for variable frequency transformers is specifically designed for performance testing of transformers and is suitable for various testing requirements of current transformers and voltage transformers in power systems.
② The universal tester is suitable for measuring various electronic components and circuits, not limited to transformers.
3. Testing accuracy and efficiency:
① The comprehensive tester for variable frequency transformers adopts variable frequency technology and digital signal processing technology, which can generate pure test voltage and current waveforms, improve testing accuracy, and simplify the testing process and shorten testing time through automatic testing mode.
② Although the universal tester also provides high-precision measurements, it may not be able to achieve the specialized accuracy and efficiency of the variable frequency transformer comprehensive tester in transformer testing.
4. Portability and ease of operation:
① The comprehensive tester for variable frequency transformers is designed to be compact, small in size, light in weight, easy to carry to the site for use, and has a user-friendly interface that is easy to get started with.
② Although the universal tester also has a certain degree of portability, it may not be as convenient and efficient as the comprehensive tester for variable frequency transformers in on-site testing of transformers.
5. Application scenarios:
① The comprehensive tester for variable frequency transformers is mainly used in power research institutes, transformer manufacturers, preventive testing in power departments, as well as handover testing in engineering units and cabinet enterprises.
② Universal testers are widely used in various electronic application fields, such as electronic engineering, product development, debugging, and maintenance.
