Transformer short-circuit impedance tester, suitable for low-voltage load impedance testing in power transformers (single-phase or three-phase) delivery, overhaul, pre-test and handover test.
The principle is to test the short-circuit impedance (%) of the power transformer on the spot, and compare it with the nameplate value or the factory value. After the factory test, the winding displacement and deformation caused by the serious fault current during transportation, installation and operation can be found. And other defects.
Transformer low-voltage short-circuit impedance tester, without an external voltage regulator, one-time wiring, only need to input parameters, it can automatically perform three-phase testing and automatically calculate the impedance error percentage, the test results are very intuitive, and it is a field test for whether the transformer has winding deformation Quickly test the instrument.
1. The instrument uses AC220V low-voltage power supply, which can automatically apply current to the AB, BC, and CA high-voltage windings of the transformer, collect data synchronously, and automatically calculate the impedance error percentage. The test results are very intuitive.
2. One-time wiring, three-phase test can be automatically completed without reversing the test line.
3. The instrument can be used for single-phase test or three-phase test; it can be tested manually or automatically.
4. With output current limiting function, it is suitable for samples with any impedance.
5. The test product can be measured without an external voltage regulator.
6. It has the function of measuring zero sequence impedance.
7. It has the function of measuring inductance.
8. Large-screen LCD display, Chinese menu, the operation is very simple, you can complete the operation according to the prompts on the screen.
9. It has the functions of printing and storage; it has the characteristics of high test accuracy, high level of automation, small size and light weight.
