The transformer ratio tester mainly detects the transformer ratio parameters. The transformer transformation ratio refers to the voltage or current ratio between the primary winding and the secondary winding, that is, the ability of the transformer to convert the voltage or current. The transformation ratio is an important parameter to measure the performance of the transformer, and the magnitude of the transformation ratio can be calculated by measuring the voltage or current value between the primary and secondary windings of the transformer. The transformation ratio of the transformer is crucial for the operation of the power system, which determines the magnitude and frequency of the output voltage or current of the transformer, and affects the stability and efficiency of the power system.
Therefore, in the design and maintenance process of the power system, it is necessary to pay close attention to the transformation ratio of the transformer to ensure that it meets the requirements of the power system. Power testers need to regularly test the transformer ratio to ensure the safe operation of the power system. The following is an introduction to the main functions and characteristics of the transformer ratio tester.
The new transformer ratio tester meets the needs of a wide range of users. The main functions and characteristics of transformer ratio tester:
1.Automatic measurement of wiring group: automatic measurement of the wiring group of the transformer, so that the wiring method of the transformer is clear at a glance, which is convenient for the staff to connect the transformer.
2.Automatic group conversion: According to the wiring group of the transformer under test, the group conversion can be carried out automatically, so that the tester can better adapt to the transformer of various wiring methods.
3.Automatic phase switching: The phase sequence can be automatically switched according to the wiring mode of the transformer under test, so that the tester can accurately measure the transformation ratio of the transformer.
4.Automatic range switching: The range can be automatically switched according to the size of the transformer under test, so that the tester can accurately measure the ratio of the transformer.
5.Automatic calibration: It can automatically correct the error of the tester to ensure the accuracy of the measurement results.
6.Relative error can be automatically calculated after entering the standard ratio: The relative error between the input standard ratio and the actual ratio can be automatically calculated, allowing the staff to better understand the performance of the transformer.
7.After a measurement is completed, the test voltage can be automatically cut off: the test voltage can be automatically cut off after a measurement is completed, so as to avoid damage to the instrument due to excessive voltage.
8.Measuring an on-load transformer with only one ratio: The ability to measure the ratio of an on-load transformer with only one ratio input greatly simplifies the testing process.
