Description:
- Built-in standard current transformer with the same radio as the tested CT , and 0.05 accuracy
- 7-inch, 800x600 dot matrix color LCD, with the tested CT’s radio error, angle difference and the secondary loop load shown simultaneously on the same screen
- No standard CTs, current boosters, load boxes, voltage regulation boxes and heavy current leads are needed for on-site tests.
- Automatically complete all error tests at the stipulated test points.
- Test function for CTs’ radio, DC internal resistance and voltage load box.
- Test functions for CTs’ radio and internal resistance of secondary windings.
- Intelligent identification and alarm functions for wrong wiring, incorrect radio and polarities etc.
- Indicate the test results(qualified or disqualified)
- Max. Data storage for on-side tests: up to 1000 groups
- Test data can be on site printed out or downloaded to USB drive.
- Test data management software.
- Shock=proof, robust and HV resistant plastic packing case, ensuring the safety of operators and the system.
