Debugging Complete Comprehensive Test Bench Switchgear Power-on Test Bench
Debugging Complete Comprehensive Test Bench Switchgear Power-on Test Bench Product Features:
1. Can accurately measure the capacity of various transformers, 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. Can automatically perform waveform distortion correction, temperature correction, voltage correction, and current correction. The operator only needs to input the correction index according to the transformer type, and the instrument can automatically calculate the corrected result. It 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 range expansion measurement, and can measure test objects with any parameters;
5. Wide voltage range: maximum voltage measurement up to 750V, accuracy guaranteed without switching gears. It will not damage the instrument due to incorrect voltage gear selection;
6. Large screen, high-brightness LCD display, full Chinese menu and operation prompts to achieve friendly human-machine dialogue, buttons make operation easier, wide-temperature LCD with brightness adjustment, adaptable to winter and summer seasons;
7. Users can print out the test data at any time through the micro printer.
