2. Relative humidity
3. Rated Primary Current:5-5000A 5A,1A
4.Rated secondary current:5 1A
5 Accuracy Class 0.05S
6. Allow long-term work under the rated current; More than120A across the core.
Precautions:
1. The current of standard CT and tested CT must be the same in CT calibration.
2. Follow the given wiring diagram strictly.
3. Test whether the load box is accurate or not before calibrating the transformer.
4. Forbid secondary winding opening during the calibration.
5. Select demagnetization before calibration.The wiring diagram is shown in figure 5.
Short out the secondary winding before cutting off the power when the demagnetization is finished.
6.Principle wiring diagram of CT with large current generator is similar to above diagram. They are the same except the output winding of large current generator and primary winding of transformer are the same one.

Transformer Manufacturers in and , Suppliers and exporters. Our offered Transformers are designed for keeping different customers and their requirements in mind, we use only superior quality raw material while the transformers which make us trusted Transformer Manufacturers in . Being a leading Transformer Manufacturers In we have a wide scope of our items including Control Transformer, Step-down Transformer, etc.
In the process of semi finished and finished production of power transformers, before the newly installed transformers are put into operation and according to the state Grid's preventive test rules, it is required to test the transformer's turn ratio or voltage ratio regularly.The traditional variable ratio bridge operation is tedious, the reading is not intuitive, and the necessary conversion, the test result is only one phase change ratio value.The transformer transformer ratio tester overcomes the shortcomings of the traditional transformer ratio bridge test, the screen uses a large screen high resolution LCD screen, convenient to use in the field, with Chinese menu prompt function, simple and intuitive operation, a complete three phase change ratio test, test speed, high accuracy.
