Transformer CT PT analyzer Comprehensive Characteristic Tester
Product description
It is designed for automatic testing of protection and metrology CT/PT, and is also suitable for laboratory and on-site testing both.
Main features
Support for detecting CT and PT both
1. Three sets of CT tests can be tested at the same time, finished one time, and the operation is simple.
2. Meet the requirements of GB1207, GB1208 and other regulations.
4. All inspection items can be completed in a single instrument without external auxiliary equipment.
5. Comes with a micro quick printer and can print test results directly on site.
6. With intelligent controller, which is easy to operate.
7. Large screen LCD, graph displays the ports.
8. Automatically show the CT/PT (excitation) inflection point values based on the procedure.
9. Automatically show 5% and 10% error curves.
10. 3000 sets of test data can be saved and will not be lost even after power failure.
11. Support U disk save the data, can be read through a standard PC, and generate a WORD report.
12. It's compact and lightweight, its weight is less than 22Kg, very good for field testing.
