Products Features

The KDHG-A Comprehensive Transformer Tester is a multifunctional on-site testing instrument specifically designed for testing transformers, including volt-ampere characteristics, turns ratio, polarity, error curves, calculation of knee points, and secondary circuit inspections. During testing, you only need to set the test voltage/current values without configuring parameters like step size or segmentation points. The device can automatically increase voltage/current and quickly display test results, such as the volt-ampere characteristic curve, turns ratio, or polarity. It supports data saving and on-site printing, eliminating the need for manual voltage adjustment, manual recording, or curve plotting. Additionally, test data can be uploaded to a computer via a USB interface for editing, saving, or printing. With its simple and convenient operation, the KDHG-A significantly improves work efficiency and is a cost-effective, high-tech product.

 

1. **Safe and Reliable:** Utilizing MBC power control technology, the device operates on a single-phase AC220V input power, with the working power and power supply sharing a single input port. This design is more scientific and reasonable, ensuring safer and more reliable operation. *Note:* Other similar products use separate inputs for working power and power supply, requiring three-phase AC380V dual live wire input to meet testing requirements, which poses safety hazards such as electric shock or even serious accidents. 2. **Complies with National Maintenance Standards:** The device outputs true voltage and current values, with standard sine waveforms at a frequency of 50-60Hz. It can effectively simulate the real state of transformers, fully complying with national maintenance regulations. 3. **High Output Capacity:** With a single AC220V input, the maximum output voltage is 0-1000V, making it highly suitable for on-site maintenance. 4. **Comprehensive Functionality:** Capable of testing CT/PT volt-ampere characteristics, turns ratio, polarity, 5% and 10% error curves, CT primary current, and CT demagnetization, achieving multiple functions with one device. 5. **Simple Wiring Method:** The device uses a single power input port, ensuring safe and straightforward wiring, which is ideal for on-site use. This reduces labor intensity and improves work efficiency. 6. **Wide Testing Range:** *Note:* The testing range does not require external voltage or current boosters. 7. **Fast Printing:** Equipped with a thermal printer that automatically selects and prints data for typical reports, making it highly suitable for on-site data comparison. 8. **Large-Capacity Flash Storage:** Capable of storing up to 1000 sets of test data, which remains intact even after power loss. 9. **USB Interface:** Supports USB flash drive storage functionality. 10. **Compact and Lightweight:** Designed for easy use during on-site operations.
