Used to measure the DC resistance of a large transformer wire
- Electric
+ 1 phase: 1A, 5A, 10A, 20A, 40A
+ 3 phases: 1A, 5A, 10A, 20A
- Measuring range:
+ 1 phase: 1A: 10mΩ ~ 20Ω 5A, 1mΩ ~ 4Ω
10A: 1mΩ ~ 2Ω 20A, 1mΩ ~ 1Ω
40Ω: 1mΩ ~ 0.5Ω
+3 phases: 1A: 10mΩ ~ 6Ω (per phase)
5A: 1mΩ ~ 1Ω (per phase)
10A: 1mΩ ~ 0.6Ω (per phase)
20A: 1mΩ ~ 0.3Ω (per phase)
Accuracy: ± 0.2% (full range)
Resolution: 0.1μΩ
Memory: 150 groups
Power supply: AC 220V ± 22V, 50Hz ± 2 Hz
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.
