HZ-3110B HZ-3120A HZ-3140A HZ-3150A HZ-3110 Transformer DC Winding Resistance Tester-1

The DC resistance is the transformer’s semi-finished product, finished product test, installation, commissioning test, and electric part prevention test necessary test project, the transformer coil can effectively find the device welding, connecting parts loose, missing unit, disconnection, and other manufacturing default and other hidden danger occurred after operation. ■ It can measure DC resistance of transformer, motor, cable, etc ■ Which model of DC resistance is chosen? How to choose the model? 1. Transformer DC resistance: the model selection is related to the transformer capacity and voltage level. 2. Motor DC resistance: the model selection is related to the motor capacity. Generally lOAis recommended. If the motor capacity reaches hundreds of thousands, 20A is recommended. 3. Cable DC resistance: the model selection is related to cable length, voltage grade and cross-sectional area.
