XLTR Series DC Resistance Tester
一、概述 General Introduction
During transformer manufacture, direct current (DC) resistance test is necessary during half-manufacture, out-of-factory, installation and acceptance procedure. Through the test, some problems or danger can be found concerning the material, welding, connection, strand and lines. To meet fast DC resistance test demand, our company developed XLTR series DC resistance tester. The equipment adopts new power technology, and features with small volume, small weight and large output current. The equipment is controlled by single plate device and automatically completes self-inspection, data procession and display. Also it has function of automatic discharge and discharge indication. The equipment has high precision and is easy to operate. Therefore, it realizes the fast measure of transformer DC resistance.
