Quotation for DC Resistance Tester

10A DC Resistance Tester Lithium Battery (Plastic Case)

summary:

The DC resistance of transformers is a necessary test item for semi-finished and finished products in transformer manufacturing, factory testing, installation, handover testing, and preventive testing by the power department. It can effectively detect manufacturing defects such as material selection, welding, loose connection parts, missing strands, and broken wires of transformer coils, as well as hidden dangers after operation. In order to meet the needs of rapid measurement of transformer DC resistance, the company has developed a DC resistance tester using its own technological advantages. transformerDC resistance testerThis instrument adopts a new power technology, which has the characteristics of small size, light weight, high output current, and can automatically adjust according to the load size. The whole machine is sampled by dual chips, with higher accuracy. It automatically completes self checking, data processing, display, printing and other functions, and has automatic discharge and discharge indication functions. The instrument has high testing accuracy, easy operation, and can achieve rapid measurement of transformer direct resistance.

The measurement of DC resistance of windings is one of the routine tests for transformers, with the main purpose of checking whether the connections or mechanical characteristics between windings, windings and leads are good, whether the resistance between each phase winding is balanced, etc., to ensure the safe operation of transformers.

The series of transformer DC resistance testers developed and produced by our company use a 32-bit ARM core as the processing core to control the entire machine, automatically complete functions such as self calibration, stable current judgment, data processing, and resistance display, and can measure the DC resistance of various types of transformers and transformers.

safety measures

1. Before using this instrument, be sure to read this manual carefully.

2. The operator of the instrument should have general knowledge of using electrical equipment or instruments.

3. This instrument can be used both indoors and outdoors, but should be avoided from places such as rain, corrosive gases, excessive dust, high temperatures, and direct sunlight.

4. Instruments should avoid severe vibrations.

5. The maintenance, care, and adjustment of instruments should be carried out by professionals.

6. After the test is completed, turn off the power first, and then remove the test line.

7. Measurement without load adjustment0The transformer must wait for the discharge indicator to stop before switching gears.

8. During the testing process, it is prohibited to move the test clamp and power supply line.
