It is a high-precision replacement product for DC single and double arm bridges. The DC resistance fast tester adopts advanced switching power supply technology and displays measurement results on a dot matrix LCD. It overcomes the disadvantage of other similar products where LED display values are inconvenient to read in sunlight, and also has an automatic arc suppression function. It is an essential test item after transformer handover, major repair, and tap changer changes. Under normal circumstances, using traditional methods (bridge method and voltage drop method) to measure the DC resistance of transformer windings and high-power inductive equipment is a time-consuming and labor-intensive task. To change this situation, shorten measurement time, and reduce the workload of test personnel.
Usage Tips for High-Precision Dual-Channel Transformer DC Resistance Tester:
1. Before measuring the no-load tap changer transformer, be sure to reset. After discharge, wait until the discharge prompt sound ends and the prompt message disappears before switching the tap changer.
3. After the test, press the "Reset" button. Be sure to wait until the discharge indicator light goes out and the prompt message disappears before turning off the power and disconnecting the wires.
4. During the test, avoid power outages or test clamp detachment.
5. Connect the ground wire before powering on, and disconnect the ground wire after the test.
