- Full-featured , meet all kinds of CT (e.g.: protection, measuring, TP) excitation characteristics ( i.e. voltage characteristics ), ratio, polarity , secondary winding resistance, secondary load, ratio error and phase angle error and other testing requirements , also for various types of PT electromagnetic unit excitation characteristics, ratio, polarity , secondary winding resistance , ratio error and phase angle error and other testing requirements.
- Automatically gives the knee voltage / current, 10% ( 5% ) error curve , accuracy limit factor (ALF), instrument security factor (FS), secondary time constant (Ts), remanence coefficient (Kr), saturated and unsaturatied inductors and others CT, PT parameters.
- Meet IEC60044-1, IEC60044-6 CT/PT standard.
- Based on an advanced low-frequency testing theory, able to test knee point of the CT test up to 30KV.
- Device can store 2000 groups of test data, non-volatile. After the test is completed with U disk to the PC, data analysis software, and generate reports in WORD file.
- Testing is simple and convenient, one button complete CT resistance, excitation, ratio and polarity tests, except load test , CT various other tests are using the same wiring.
- Easy to carry, instrument weight<9KG.
