Simplified Comprehensive Transformer Test Bench Automatic Transformer Tester System
These systems are a revolution in the fully automatic testing of power and distribution transformers. A complete new development using state of the art intuitive software, operated over a big touch screen monitor offers unique user comfort. from a small portable unit with a rating of 1000VA to power transformer. 
1.Full computer automatic operation: by using mouse, all the tests can be finished and test reports can be made out and printed out; Test data can be recalled by inputting data serial number; Can be shifted to manual operation.
2. By inputting basic parameters of the experiment (capacity, HV and LV), grades of instrument transformers can bechosen automatically.
3. Automatically choosing grade of intermediate transformer
4. Automatically shift compensation capacitor, choosing test circuit
5. Automatically over-voltage, over-current protecting and alarming
6. Automatically collecting data, saving data; automatically resuming to initial status
7. Automatically generating and printing ex-work test reports
8. Data monitoring adopts high precision power analyzerwhich is our patent.
9. By adopting new-style compensation capacitors, capacity of regulator is not needed to be raised and so machine cost is much less and electric consumption is also much less.
10. Multiple safety protection is achieved by software, hardware and system self-interlock; Primary circuit and secondary circuit of control system are separate and so raise safety of operator and experiments.
11. Adjustment of inductive conductor is by inverter control motor, higher efficiency and precision.
12. This test bench is also suitable for ex-work test of repaired 35kV, 6300kVA transformers.
13. This system can also fulfill transformer harmonic analyzing test (loss tester has this function)
14. Because of high-automation requirement, there will be one high-voltage switchgear panel special for controlling output of intermediate transformerand so achieving automatic control by industrial computer.
15. Reserved ZIP sockets for future 35kV transformer testing for future purpose
