DDG-500A Hipot Large Primary Current Injection Tester High Current Generator

The DDG-500A High Current Generator is an essential device for high current testing in the power and electrical industries. It is widely used in power plants, substations, electrical manufacturing plants, and research institutions. The device is designed for short-term or intermittent operation and is characterized by its compact size, lightweight construction, and ease of use and maintenance.

• Resists high heat, humidity, and salt spray for tropical island use.
• Runs stably at -40°C, cold-proof and anti-condensation.
• IEC compliant, with complete calibration certificates provided.
• Local support available: spares, on-site training, and instrument calibration.

1. Uses a beautiful and elegant PVC panel.
2. Directly displays the test values of primary and secondary currents for easy observation and recording.
3. High power, small size, and strong load capacity.
4. Six-and-a-half digit LCD display for voltage and current, providing higher display accuracy and more accurate experimental results (unique domestically).
5. 128×64 dot matrix LCD display for more intuitive data presentation and quicker readings (unique domestically).
6. Instrument display lock function, particularly useful for more accurate and faster readings during transformer ratio tests.
7. Polarity measurement, with automatic measurement of transformer polarity without the need for a separate test.
8. Automatic detection function of the ratio.
9. Newly added self-locking function (unique domestically).
10. Small size and light weight, only 30% to 70% of similar products, making it very convenient to carry.
