2. Application:

EGZC-III series Winding DC Resistance Tester is designed to measure DC resistance of inductive devices, 

such as transformers and power inductors. Differences from conventional type are that it can test 

three phases simultaneously, so test speed will be even faster, which can save more time for 

the operating stuff, it is an optimal device for measuring transformer winding DC resistance of large 

power inductance equipment, especially when you have too many objects tested and time is limited..



3. Main Features

>For on-load variable transformer,no need to discharge,just adjust tap switch directly;

>The measurement time is 1/3 of tradition single phase measurement,that working time and labor intensity is shorten;

>Big screen LCD display,clear and visual,easy operation;

>Built-in panel printer and big capacity memory, easy to get printing result and convenient to storage data;

>Stable data,fast testing and good repeatability,suitable for transformer DC resistance on-site measurement.



4. Main Configuration:

1)  Power Frequency Manual Control Desk          25kVA                     1 set;

2)  Oil Immersed Test Transformer Body              25kVA/100kV           1 set;
