Product Description

Circuit Breaker Impedance Tester

Darui Electric recommends for you

Product Features:

1. The instrument is compact and lightweight.

2. The instrument uses voltage and current synchronous AC sampling and signal digital processing technology, ensuring accurate measurement data.

3. The instrument adopts single-phase measurement mode. After selecting the transformer connection, three measurements can automatically calculate the short-circuit impedance of each phase.

4、 The instrument has the function of automatically converting low current test results to rated current, suitable for field use.

5、 The instrument can simultaneously measure voltage, current, and power, as well as the frequency of the applied power supply.

6、 Built-in non-volatile memory allows long-term storage of measurement data, and the instrument comes with a built-in printer.

7、 Large-screen LCD display with full Chinese menus and operation prompts, making operation simple and intuitive. The LCD is clearly readable even under direct sunlight.

The low-voltage short-circuit impedance test is a direct method to verify whether the windings of a transformer have deformed after being subjected to short-circuit current impact during operation, or mechanical impact during transportation and installation. It is of great significance for determining whether the transformer can be put into operation, and is also one of the bases for judging whether the transformer requires disassembly inspection.

The transformer short-circuit impedance tester is an instrument used for low-voltage short-circuit impedance measurement of main transformers at 35kV and above, both in the field and in laboratory conditions.
