Transformer Testing Transformer
: Transformer Testing Transformer Features
>Based on advanced frequency conversion principle, the output is only up to 180V AC voltage and 12A AC current, yet it can handle CT testing with knee point up to 60KV.
>Comprehensive functions, suitable for excitation, ratio, phase, polarity, secondary winding resistance, burden, ratio error, and phase error tests of various types of CTs and PTs, including steady-state and transient characteristics.
>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 tests and calculations on CTs and PTs according to different standards such as GB1208-2006 (IEC60044-1), GB16847-1997 (IEC60044-6), etc.
>User-friendly interface, 5.7-inch graphic LCD display, full Chinese graphical interface.
>Operated by rotating optical mouse, simple, fast, and easy to master.
>The device can store 3000 sets of test data, which will not be lost after power failure.
>Built-in printer on the panel can automatically print generated test reports.
>Convenient testing: except for burden test, all other tests are based on the same wiring.
>Easy to carry, device weight <9Kg.
