The DC resistance of transformers is a necessary test item for semi-finished and finished products in transformer manufacturing, including factory testing, installation, overhaul, change of tap changer, handover testing, and preventive testing by the power department. It can check the welding quality of the winding joints and whether there is any inter turn short circuit in the winding. It can also check whether the contact at various positions of the voltage tap changer is good, whether the actual position of the tap changer matches the indicated position, whether the outgoing wire is broken, and whether there are broken strands when multiple wires are wound together. In order to meet the needs of rapid measurement of transformer DC resistance, our company has developed the ZSR10A transformer DC resistance tester. This instrument adopts a new power supply technology, which has the characteristics of small size, light weight, high output current, good repeatability, strong anti-interference ability, and complete protection functions. The entire machine is controlled by a high-speed microcontroller, with a high degree of automation and automatic discharge and discharge alarm functions. The instrument has high testing accuracy, simple operation, and can achieve rapid measurement of transformer direct resistance.
