GOZ-ZDS-40A Transformer Resistance Meter(40A)

GOZ-ZDS-40A Transformer Resistance Meter(40A)
  • Transformer Resistance Meter(40A)
设备概况
   Transformer Resistance Meter 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.
    This product complies with DL/T845.3-2004, national standards GB6587 "Environmental test general program of electronic measuring instruments" and GB6593 "Quality inspection provisions for electronic measuring instruments".
    Alternative Name
    DC resistance tester , DC resistance rapid tester, transformer DC resistance tester.
