INTRODUCTION

DC resistance measurement of transformer winding is an essential test project during transformer delivery, repair and changing tapping switch. Usually, it is a time consuming task to use traditional methods (bridge method and voltage drop method) to measure transformer winding and DC resistance of high-power inductive device. In order to change this situation: shorten measurement time and reduce the staff’s workflow, our company has developed DC resistance rapid tester. The instrument using new power technology, with characteristics such as stable performance, rapid test, small size, light weight, easy operation, high measure precision and good data reproducibility, is the ideal equipment to measure transformer winding and DC resistance of high-power inductive device.

MAIN FEATURES

1,The machine is controlled by a high-speed single-chip, high degree of automation.
2,Using high-frequency switching power supply technology, high output current, suitable for medium-sized transformer DC resistance measurement
3,Perfect protection function, can be reliably protected the potential impact of the instrument, more reliable.
4,With sound discharge function, discharge indicating clear, reduce misuse.
5,Fast response, can directly convert load tap changer when measuring, the instrument automatically refresh the data.
6,Vertical chassis structure , easy field use
7,Intelligent power management technology, the instrument will always work at the minimum power state, effectively reducing the heat inside the instrument, saving energy. Uninterrupted hours of work.
8,Dot matrix LCD, with printer.
