The operational safety and high efficiency of the three -channel DC resistance test instrument are inseparable. The standardized operation can ensure its long -term stable operation and avoid unnecessary damage or safety hazards.

Most of the experienced electricians who have been engaged in the power testing industry for a long time know that it is very important and necessary to perform corresponding DC resistance tests on semi-finished and finished transformers after factory testing, installation, overhaul, and changing of tap switches. Nowadays, the test instruments we use more frequently include DC resistance testers.

Transformer DC resistance ratio (on-load) tester, is for the power industry, transformer manufacturing and field maintenance and other professional scenarios tailored to the efficient integrated solution. The equipment innovatively realizes the completion of DC resistance and ratio (on-load) testing in one wiring, which significantly improves operational efficiency and effectively saves labor costs.

In the transformer DC resistance test, it will be found that the DC resistance value of the winding will be unbalanced, the reason can be divided into human factors, winding structure and material problems and transformer defects in three cases.

The DC resistance of a transformer refers to the DC resistance value of each phase winding. The purpose of measuring the DC resistance of a transformer is to check the welding quality of the winding joints and whether there is a short circuit between the winding turns; to check whether the contact of the tap changer is good and whether the actual position of the tap is correct.

With the continuous expansion of the market, our marketing department has recently reached an important shipment milestone: we have successfully exported 3 sets of equipment to international markets. The shipment includes 2 sets of DC High Voltage Generators, which will serve customers in the USA, and 1 set of Transformer DC Resistance Tester, which will be utilized in Vietnam.

Recently, our company has received positive feedback from a customer from Vietnam, who highly praised the DC resistance tester provided by our company. The customer's affirmation not only reflects the excellent performance of the product, but also further consolidates the brand image of our company in the international market.

we are very happy that we have established business relationship with our customer in Mexico
