Technical Featuresl Variable-Frequency Test Method Excitation characteristic of CT/PT and 10% error curve are tested through advanced variable-frequency test method. At most 180V AC voltage and 5A AC current are needed for CT test whose knee point reaches up to 30kV.
l Boost Current Function With current booster, the maximum current can reach 150A.
l Full Test Function Steady and transient state characteristic tests of various types of CT/PT, including excitation, ratio, phase, polarity, secondary winding resistance, burden, ratio error and phases displacement can be tested.
l Automatic Display Parameters such as knee point current and voltage, 10% error curve, 5% error curve, accuracy limit factor (ALF), factor of safety (FS), secondary winding time constant (Ts), remanence coefficient (Kr), accuracy class, saturated and unsaturated inductance are displayed automatically.
l The device can test and calculate CT/PT according to different standards such as GB1208-2006(IEC60044-1) and GB16847-1997(IEC60044-6)
l Friendly and beautiful Chinese graphical interface, 5.7”Lens CT-VTR graphic LCD, visible in the sun.
l The device can store 3000 groups of test data which would not be lost if the device loses its power. The data can be displayed and analyzed after the test, or transferred to PC through USB disk and produce a Word file report.
l Easy to test, all the tests are using the same wire connection except the load test.
l Portable, weight < 9Kg。
