Product Description

The Transformer Direct Resistance Tester is an indispensable test item for transformers after handover, major maintenance, and change of tap switches. The regulations stipulate that during transformer handover, major maintenance, minor maintenance, change of tap position, fault inspection, and pre-testing, the direct resistance of the transformer windings must be measured, with the purpose of:

Inspect the soldering quality of internal wires and leads within the winding.

2. Check for good contact at all positions of the tap changer.

3. Inspect for any breaks in the windings or leads.

4. Verify the correctness of the parallel circuit, and check for any instances of a winding made from several parallel wires having one or more breaks.

5. Inspect for any short-circuit phenomena between layers and windings.

6. The Transformer Direct Resistance Tester utilizes advanced power supply technology, featuring rapid measurement, compact size, ease of use, and high measurement accuracy. It is an ideal device for measuring the direct resistance of transformer windings and high-power inductive equipment.

7. The Transformer Direct Current Resistance Tester meets the requirements of the national standards GB6587-86 "General Outline for Environmental Tests of Electronic Measuring Instruments" and GB6593-86 "Regulations for Quality Inspection of Electronic Instruments."
