Transformer winding resistance meter

DC Resistance Tester

Product introduction
1.Transformer Resistance Meter is an essential test project during transformer delivery, repair and changing tapping
switch.

 
2.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.

 
3.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
rapid test, small size, light weight, easy operation and high measure precision, is the ideal equipment to
measure transformer winding and DC resistance of high-power inductive device.

 
4.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".

5.Alternative Name:DC resistance tester , DC resistance rapid tester, transformer DC resistance tester.

Product parameters

Product introduction 

Winding Resistance Ohmmeter is a very important test project. In the "electrical equipment test procedures", it ranks second in transformer test project. "Electrical equipment test procedures" provides that it is necessary to measure the DC resistance of transformer windings during transformer transfer, heavy maintenance, light maintenance, changing tap joint position, troubleshooting and pre-test, which aims to:
1)Check the welding quality of lead and down-lead within the winding;
 2)Check whether the contact of each tapping switch position is good;
 3)Check whether the winding or down-lead is broken
 4.Check whether the parallel branch is correct and whether the winding winded by several parallel wires has one or several disconnection;
 5)Check whether layer or inter-turn is short circuit 

 6)Alternative Name:DC resistance tester , DC resistance rapid tester, transformer DC resistance tester.
