I.System Introduction

Transformer Demagnetization Tester,it is a special equipment to eliminate the remanence after the DC resistance test of a large powe. It is very important to protect the transformer from the impact of the inrush, the safe operation and the prolongation of the life of the transformer.

Transformer Demagnetization Tester，Adopt advanced and reasonable compound current method technology，demagnetize power transformer transformer，the demagnetization detection is also quantified.

1.Characteristics

l Apply to the removal of remanence before the 35KV and above large power transformers are put into operation.

l The advanced composite current degaussing method is adopted, and the current impact is small in the degaussing process.

l Fast demagnetization speed, three-phase transformer demagnetization once or twice.

l Automatic demagnetization and manual demagnetization of the instrument.

l It has the functions of initial remanence detection and remanence detection after demagnetization. The primary wiring can complete the measurement of demagnetization and remanence,and display the curves before and after test.

l The wiring is simple, and the demagnetization test can be carried out directly by using the test line of the DC resistance tester.

l Digital current adjustment is adopted with high control accuracy.

l It adopts 5-inch color touch screen control, which is easier to operate. The system interface can be switched between Chinese and English.

l The test results are automatically stored, and the data before and after degaussing is completely recorded without manual storage.

l The report can be printed directly and stored in the U disk.

l Analysis software management is highly humanized and intelligent. After setting parameters, all measurement can be completed by pressing one key.

l The software interface is simple and intuitive, and the menus of analysis, storage, report export and printing are very clear.
