SXFA-III CT/PT Analyzer is designed to test on protection and measurement CT/PT automatically, suitable for laboratory and on site testing.

♦  Support CT and PT testing.

♦  The external connected auxiliary device is unnecessary.

♦  Build-in printer.

♦  Intelligent controller, easy to operate.

♦  Large LCD screen, English interface, cursor operation, display test result and curve by real-time.

♦  Auto provides CT/PT (excitation) knee point value.

♦  Auto provides 5% and 10% error curve.

♦  3000 groups’ data storage no lost even power failure.

♦  U disk to save data, and generate to test report via PC.

♦  Light weight, less than 22kG, suitable for on-site test.
