I. Transformer Capacity and No-load/Load Tester ZYYB Features
1. Can accurately measure the capacity of various distribution transformers, passive measurement, convenient and accurate.
2. Can measure various types of transformer no-load current, no-load loss, short-circuit voltage, short-circuit loss, and zero-sequence impedance.
3. Can automatically perform waveform distortion correction, temperature correction, voltage correction (no-load test under non-rated voltage), and current correction (short-circuit test under non-rated current). The operator only needs to input the correction index based on the transformer type, and the instrument will automatically calculate 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 connection of voltage transformers and current transformers for extended range measurement, and can measure test objects with any parameters.
5. Wide voltage range: maximum voltage measurement up to 750V, ensuring accuracy without switching gears. It will not damage the instrument due to incorrect gear selection.
6. Large screen, high-brightness LCD display, full Chinese menu and operation prompts for friendly human-machine interaction, touch buttons make operation easier.
7. Users can print the test data at any time through the micro printer.
