With the continuous advancement of technology in recent years, the modularization and intelligence level of power construction has been continuously improved, and some CT volt-ampere characteristic tests, PT volt-ampere characteristic tests, CT polarity tests, PT polarity tests, CT Power grid test items such as the transformation ratio polarity test and the PT transformation ratio polarity test, but the old-fashioned electromagnetic transformers are increasingly unable to meet these test requirements, and a new generation of comprehensive transformer testers came into being.

When power companies actually purchase a comprehensive tester for transformers, they need to ensure that the transformer can accurately measure high-frequency components and aperiodic components according to the actual situation and needs of the company, and can automatically calculate any point of CT Result parameters such as error curve. Especially in the construction of substations, the transformer tester plays a very important role, because it has high stability and resistance to high voltage, and is especially suitable for the working environment of the substation.

Transformers can also play a very important role in the secondary circuit. Generally, a comprehensive transformer tester is used in the secondary circuit, which can significantly reduce the length of the wire and cable, and ensure the control of the interval and the compactness of the substation structure design. While reducing the cost of the power grid, it also improves the stability and security of the power grid, which can do two things with one stone.

Because of its good safety, reliability and wide application, the transformer tester has replaced the old-fashioned electromagnetic transformer, and has increasingly become an indispensable important power equipment for power companies. Therefore, the selection and application of transformers should be cautiously carried out to realize their value as much as possible.
