Goldhome's on-site current transformer tester is developed using advanced testing technology, large-scale electronic circuit design, and in compliance with relevant national standards. It addresses the issues of high workload and cumbersome operations associated with on-site verification of current transformers, while offering reliable performance and powerful functionality.
- Tests are conducted using a power supply with a frequency close to power line frequency to prevent on-site power line electromagnetic radiation and series interference.
- The measurement range is wide, extending from 5A/5A to 31,500A/5A or 5A/1A to 6,300A/1A.
- Includes functions for testing current transformer turns ratio and secondary winding resistance.
- Features an 800×600 high-resolution large-screen TFT color LCD touchscreen with a user-friendly interface and operation design; touchscreen-assisted operation makes usage more convenient and efficient.
- Utilizes precise software algorithms to further enhance the accuracy of measurement data.
- Intelligently detects external wiring conditions and alerts users to wiring errors, incorrect turns ratios, and polarity errors.
- It automatically rounds test data to the nearest integer and determines whether it falls within tolerance limits. Data outside tolerance limits is displayed in orange, and a "Out of Tolerance" message appears in the lower-right corner of the window, providing an intuitive and clear view of the transformer's performance characteristics.
- It is the first in China to offer the capability to simultaneously test both the turns ratio and polarity of voltage transformers.
