l The tester has a built-in micro printer, with Chinese character print output, allowing test results to be printed directly on site.
l Built-in protection circuit to avoid instrument damage and personnel accidents.
l Long-life touch keys for easy operation; most operations can use default settings, one-key operation throughout.
l Built-in high-energy power supply can complete all test items, and the instrument does not need external power supply or auxiliary equipment such as voltage regulators and current boosters during on-site testing.
l Unique power-saving mode ensures completion of field testing of multiple transformers of various models.
l Can test transformer capacity at non-rated tap positions.
l Stable test data with good repeatability.
l Simple wiring; only two test clips are needed to complete the test, without phase distinction, any two phases can be selected.
Functional Features
Edit
1. Can accurately measure the capacity of various distribution transformers, passive measurement, convenient and accurate.
2. Can measure no-load current, no-load loss, short-circuit voltage, short-circuit loss, and zero-sequence impedance of various types of transformers.
3. Automatically performs 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, which is very suitable for units that do not have 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 any parameters.
5. Wide voltage range: maximum voltage measurement up to 750V, ensuring accuracy without switching gears. No damage to the instrument due to incorrect voltage gear selection.
���6. Large screen, high brightness LCD display, full Chinese menu and operation prompts for friendly human-machine interaction, touch keys for easier operation, wide temperature LCD with brightness adjustment, adaptable to winter and summer seasons.
7. Users can print test data at any time using the micro printer.
