China Single Phase DC Transformer Test System Winding Resistance Tester

DC Transformer Test System Winding Resistance Tester
General Information:
SXZR is single phase DC winding resistance tester which designed specifically to measure DC resistance values of transformer windings and any DC resistance of an inductive device.
Features:The whole machine is controlled by high speed single chip microcomputer, with high automation and easy operation.The instrument adopts the new power supply technology, has many current levels, the measuring range is wide, the current can be automatically selected according to the load, which is suitable for the DC resistance measurement of small and medium-sized transformers and voltage transformers.The protective function is perfect, can protect the impact of the back electromotive force to the instrument reliably, the performance is more reliable.With sound discharge alarm, clear discharge indication, reduce mis-operation.With fast response speed, the load tap changer can be directly converted to the measured state, and the instrument can automatically refresh data.Intelligent power management technology, the instrument always works in the state of minimum power, effectively reduce the internal heat of the instrument, save energy.65 K True Color liquid Crystal of Ultra small Pixels in 320x240 Lattice.The instrument comes with the calendar clock and power down storage. It can store 1000 sets of test data, and it can be consulted at any time.The instrument is equipped with RS232 and USB interface, which can communicate with computer and U disk.
