l The tester is equipped with a built-in micro printer for Chinese character printout, allowing test results to be printed directly on site.
l Built-in protection circuit prevents instrument damage and personnel accidents.
l Long-life touch keys for easy operation; most operations can be performed using default settings, with one-key operation throughout.
l Built-in high-energy power supply can complete all test items; during field testing, the instrument does not require external power supply or auxiliary equipment such as voltage regulators and current boosters.
l Unique power-saving mode ensures completion of field testing for multiple transformers of various models.
l Transformer capacity testing can be performed at non-rated tap positions.
l Test data is stable with good repeatability.
l Simple wiring: only two wiring clamps are needed to complete the test, regardless of phase sequence; any two phases can be selected.
Functional Features
Edit
1. Accurately measure the capacity of various distribution transformers without external power, convenient and accurate.
2. Measure no-load current, no-load loss, short-circuit voltage, short-circuit loss, and zero-sequence impedance of various types of transformers.
3. Automatically perform waveform distortion correction, temperature correction, voltage correction (no-load test at non-rated voltage), and current correction (short-circuit test at non-rated current). The operator only needs to input the correction index based on the transformer type, and the instrument automatically calculates the corrected results, making it very suitable for units that lack conditions for short-circuit tests on slightly larger capacity transformers.
4. Allows external voltage transformers and current transformers for range extension, enabling measurement of test objects with arbitrary parameters.
5. Wide voltage range: maximum measurable voltage up to 750V, ensuring accuracy without switching gears. Incorrect voltage gear selection will not damage the instrument.
6. Large screen, high brightness LCD display with full Chinese menu and operation prompts for user-friendly interaction; touch keys make operation easier; wide temperature LCD with brightness adjustment adapts to various seasons.
7. Users can print test data at any time using the built-in micro printer.
