transformer test bench for transformer test
I. Feature :
1.1 Adopted all data monitoring method according to the related international standard,the accuracy of data is guaranteed by the high precision power analyzer.
1.2 Primary circuit, secondary loop and interlock system are adopted to protect the system; the equipment is designed with split type; primary circuit and secondary control circuit are designed separately in the control unit to improve the security of tester and the product.
1.3 The system uses the three meter method (4P3W), instrument transformer includes six independent systems of 0.05class, which greatly improve the stability and precision of the test.
1.4 In the case of step-up testing, as the induction voltage regulator is driven by both the motor and turbine, it is hard to control test voltage accurately in the process of regulating, especially in the power frequency withstand voltage test and no-load test because of the inertia force. We adopt the frequency control method that the motor speed can be adjusted, which greatly improve the work efficiency and the accuracy of test data.
1.5 Wave analysis test can also be done with transformer by this system. (Power analyzer have this function).
II. Function :
Routine testing
1. Transformer winding DC resistance testing;
2. Transformer no-load current percentage and no-load loss testing;
3. Transformer short-circuit impedance percentage and load loss testing;
4. Transformer power frequency withstand voltage testing;
5. Transformer frequency doubling induced withstand voltage testing;
6. Transformer variable ratio group testing;
7. Transformer insulation resistance testing.
8. Temperature rise test (option)
9. Noise level measurement
more requirements can be customzied accoriding to client's requirements.
