AL104 DC Resistance Fast Tester
Implementation of standards.
GB6587-86、GB6593-86
DC resistance of transformer is a key test item in delivery test, installation, and acceptance trial of finished and semi-finished products in the manufacturing of transformer, and in preventive test of power department.
Catering to the needs of fast measuring of transformer DC resistance, the equipment is developed to have brand new power source technology with small size, light weight, high measuring accuracy and simple operation, capable of auto-completing test and data saving and functions of self discharge and discharge indication. It can save 999 groups of data, which are uploaded to upper computer through RS232 port.
Interface of equipment is designed in high dot matrix graphic LCD module, with friendly man-machine interaction and clear and sufficient indication of test procedure and working condition; adoption of intelligent and automatic design increases test efficiency and alleviates working intensity of operating staff.
The equipment has an application in measurement and analysis of inductance low resistance value of power transformers and winding of mutual inductor.
