The DC resistance test of transformers is a must-test item for semi-finished products, finished products factory test, installation, handover test and preventive test of power department in transformer manufacturing. Dual-channel DC Resistance Tester can effectively discover whether there are manufacturing defects such as looseness, missing stocks, wire breakage, etc. in the selection, welding, and connection of the transformer coil and hidden dangers after operation.
Description
In order to quickly measure the DC resistance of the transformer, the 2 channel dc resistance tester uses a new power supply technology. The DC Resistance Analyzer has the characteristics of small size, light weight and large output current.
The whole Transformer DC Resistance Tester is controlled by a single-chip microcomputer, which automatically completes the functions of self-inspection, data processing, and display, and has the functions of automatic discharge and discharge indication. The Dual-channel DC Resistance Tester has high test accuracy and simple operation, which can realize the rapid measurement of transformer direct resistance. RDZR-5AS Dual-channel DC Resistance Tester is designed for temperature rise measurement of three-core five-column large transformers. The charging and measuring speed is fast, which can meet the time requirements of the transformer temperature rise test. Dual-channel measurement, real-time sampling, and printout.
Features
1. The Dual-channel DC Resistance Tester has large output current and high voltage.
2. Dual-channel measurement, measuring two resistance values at the same time.
3. The 2 channel dc resistance tester has a complete protection circuit and strong reliability.
4. The horizontal structure is convenient for on-site operation of the transformer factory.
5. With audible discharge alarm and clear discharge indication to reduce misoperation
