Product Description
Transformer DC resistance is a must-test item in transformer manufacturing for semi-finished products, finished products, factory test, installation, overhaul, after changing the tap changer, handover test and preventive test in the power sector. You can check the welding quality of the winding joints and whether the windings have short-circuits between turns. You can check whether the contact of each position of the voltage tap switch is good, whether the actual position of the tap changer matches the indicated position, and whether the lead wire is broken. Whether there is stock breakage, etc. In order to meet the needs of rapid measurement of transformer DC resistance, the XHZ1010S transformer DC resistance tester developed by our company.
The instrument adopts a brand-new power supply technology, which has the characteristics of small size, light weight, large output current, good repeatability, strong anti-interference ability, and perfect protection functions. The whole machine is controlled by a high-speed single-chip microcomputer, with a high degree of automation, with automatic discharge and discharge alarm functions. The instrument has high test accuracy and easy operation, which can realize rapid measurement of transformer DC resistance.
320X240 dot matrix ultra-small pixels 65K true color LCD, clear display under strong light
The instrument has its own power-down storage, which can store 1000 sets of test data, which can be consulted at any time.
