Product Description

product description
GF1061 ct/pt  transformation ratio system test set is mainly used for field or lab testing, it can finish the measurements (M) and protection (P) class CT, PT and TYP class CT. Adopt 7 inch touch TFT LCD,
self-equipped mini type printer supporting field printing; supporting to use USB flash disk to dump data. The CT PT Analyzer is the most complete and easy-to-use testing system for protection and metering CTs according to IEEE and IEC standards.
Features
1. Steady and transient state characteristic tests of various types of
CT/PT
2. The use of advanced power technology, the test knee point
reaches up to 30kV
3. No external other auxiliary equipment, stand-alone to complete
all test items
4. CT test, easy to test, all the tests are using the same wire
connection except the load test
5. It carries with thermal printer, so it can print test results on site
Reference Standard
IEC 60044, ANSI/ IEEE C57.13, IEC61869, GB 1207-2006, GB 1208-2006
6. Parameters such as knee point current and voltage
7. Parameters such as 10% error curve, 5% error curve
8. With battery, working 48hours.
9. The device can store 10000 groups of test data which would not be lost if the device is power off.
10. The data can be displayed and analyzed after the test, or transferred to PC through USB disk and produce a Word
file report
11. Portability: weight <4kg, the best light ct analyzer
