KF-6408C Fully Automatic Transformer Comprehensive Tester
Product Description:
Product details

1. Main features of KF-6408C fully automatic transformer comprehensive tester

• Support detection of CT and PT

The CT ratio test adopts the voltage method, which can complete the test without the need for high current output.
KF-6408D can complete 6-channel CT ratio testing in one go, with simple operation
Meet the requirements of regulations such as GB1207 and GB1208
Without the need for external auxiliary equipment, all testing items can be completed on a single machine
Equipped with a miniature fast printer, it can directly print test results on site
Adopting an intelligent controller, the operation is simple
Large screen LCD with graphical display interface
Automatically provide CT/PT (excitation) inflection point values according to regulations
Automatically provide 5% and 10% error curves
Can save 3000 sets of test data without losing it after power failure
Supports USB flash drive data transfer, which can be read through a standard PC and generate WORD reports
Small and lightweight ≤ 22Kg, very conducive to on-site testing
