General Information:

The DC resistance of the transformer is a required test item for the semi-finished product, finished product delivery test, installation, transfer test and preventive test of the power sector in transformer manufacturing. It can effectively find the manufacturing of transformer coil materials, welding, loose connection parts, missing stock, broken wires, etc. Defects and hidden dangers after operation. In order to meet the needs of transformer DC resistance fast measurement, the instrument uses new power technology, which has the characteristics of small size, light weight, large output current and so on. The whole machine is controlled by a single-chip microcomputer, which automatically completes self-test, data processing, display and other functions, and has automatic discharge and discharge indication functions. The instrument has high test accuracy and easy operation, and can realize fast measurement of transformer direct resistance.

EPWT-20WH dual-channel DC resistance tester is specially designed for three-core five-column large-scale transformer temperature rise measurement, fast charging and measuring speed, can meet the time requirements of transformer temperature rise test, two-channel measurement, real-time sampling and printout.

Features:

◆ Large output current and high voltage.

◆ Two-channel measurement, measuring tworesistance values at the same time.

◆ Complete protection circuit and strongreliability.

◆ The horizontal structure is convenient forfield operation of the transformer plant.

◆ Acoustic discharge alarm, clear dischargeindication, reduce misoperation.
