DC Resistance Tester 40A

• Transformer Direct Current Resistance Tester can detect the contact conditions of each position of voltage tap changer and whether the actual position of tap changer is consistent with the indicated position, whether the outgoing line is broken, and whether there is broken strand in multi strand conductor parallel winding.

• In order to meet the needs of fast measurement of transformer DC resistance, our company developed RDZR-40A DC Resistance Tester. The DC Resistance test instrument adopts new power supply technology, which has the characteristics of small volume, light weight, large output current, good repeatability, strong anti-interference ability, perfect protection function and so on. 

• The whole DC Resistance test machine is controlled by high-speed single-chip microcomputer, with high degree of automation, automatic discharge and discharge alarm function. The DC Resistance test instrument has the advantages of high precision and easy operation, and can realize the fast measurement of transformer direct resistance.

• The whole DC resistance tester machine is controlled by high-speed single chip microcomputer, with high degree of automation and easy operation.

  The transformer DC resistance test instrument adopts new power supply technology, with many current ranges and wide measurement range, which is suitable for DC resistance measurement of large and medium transformers.

• The protection function is perfect, which is reliable to  protect the impact of back EMF on the instrument, and the performance is more reliable.

• Sound discharge alarm, clear discharge indication, reduce operation mistakes.

• Fast response.

• Intelligent power management technology, the instrument always works in the minimum power state, which can effectively save energy and reduce heating.

• 320x240 ultra small pixel 65K true color liquid crystal,

• The  DC resistance measurement instrument has its own calendar clock and power down memory, which can store 1000 groups of test data and can be consulted at any time

• The  DC resistance test equipment is equipped with RS232 and USB interface, which can communicate with computer and store in U disk.
