The DC resistance of transformer is a necessary test item for semi-finished products, finished product delivery test, installation, handover test and preventive test of power department in transformer manufacturing. It can effectively find the manufacturing defects of transformer coil, such as material selection, welding, loose connection parts, missing strand, broken wire and hidden dangers after operation.
BL-205 Transformer DC Resistance Tester is an innovative product, built-in large capacity lithium battery, instrument and test line using machine line integrated design, product size is small, easy to carry. The product is not only suitable for the measurement of inductive test objects such as transformer, mutual inductor and reactor, but also suitable for the measurement of resistive test objects such as copper bar, conductor and switch contact. The test speed of the instrument is fast and the accuracy is high.
