DC resistance of the transformer is a required test in manufacturing semi-finished and finished products testing, installation, commissioning test and power sector preventive trials ,which can effectively find the transformer coil selection, welding, ,loose joints, lack of stocks, disconnection and other manufacturing defects. In order to meet the DC transformer Resistance rapid measurement needs, our company using the new power technology, small size, light weight, large output current.
Machine controlled by microcomputer, auto-complete self-test, data processing, display as well as self-dynamic discharge and discharge indicator.
- 1. The device output current high, light weight.
- 2. Has a complete circuit protection, reliable.
- 3. Vertical chassis structure, easy operating on field.
- 4. Discharge alarm, discharge indicator clear, reduces misuse.
