Product Description

CTP-1000AVariable Frequency Comprehensive Transformer Characteristics Tester (Class 0.1)

Technical Features:

>Based on advanced frequency conversion principle, it outputs a maximum of only 180V AC voltage and 12A AC current, yet can handle CT testing with knee point up to 60KV.

>Comprehensive functions, suitable for steady-state or transient characteristic testing of various types of CT and PT, including excitation, ratio, phase, polarity, secondary winding resistance, burden, ratio error, and phase error.

>Automatically provides parameters such as knee point voltage/current, 10% error curve, 5% error curve, accuracy limit factor (ALF), instrument security factor (FS), secondary time constant (Ts), remanence coefficient (Kr), accuracy class, saturated and unsaturated inductance, etc.

>Can perform testing and calculation of CT and PT according to different standards such as GB1208-2006 (IEC60044-1), GB16847-1997 (IEC60044-6).

>User-friendly interface, 5.7-inch graphic LCD display, full Chinese graphic interface.

>Adopts rotary optical mouse operation, simple, fast, and easy to master.

>The device can store 3000 sets of test data, which is not lost after power failure.

>Built-in printer on the panel can automatically print the generated test report.

>Convenient testing, except for burden test, all other tests are based on the same wiring.

>Easy to carry, device weight <9Kg.
