Transformer Test System Diagnostic Equipment with Turns Ratio and DC Resistance Measurement

Product Description

Feature of KDZR-ZH Transformer DC Resistance & Turns Ratio Tester:

1. One-time wiring can complete direct resistance test and ratio test.

2. Direct resistance test function, for Yn type, Y type and △ type winding, three-phase automatic test can be adopted, and the three-phase imbalance rate can be calculated; the maximum output current is 20A, which can meet the test of low-voltage coil of distribution transformer.

3. Ratio test function, with three-phase, single-phase, Z type transformer test function; PT/CT ratio and polarity test function; blind test function.

4. Multiple wired and wireless communication interfaces facilitate instrument function expansion.

5. The instrument adopts embedded Linux operating system, which has high security, fluency, ease of use, etc.

6. The instrument adopts A7+M4 dual-core architecture, which meets both the real-time measurement and the smoothness of operation.

7. Industrial-grade 7-inch large screen display.

8. This instrument is powered by a large-capacity lithium battery with a built-in charger.
