Brief introduction
This device uses high-performance DSP and ARM, advanced manufacturing process to ensure that the product is stable and reliable, full-featured, high degree of automation, high test efficiency, is the professional testing equipment for the CT/PT industry.
Products features
1. 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.
2. 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 unsaturated inductors and others CT, PT parameters.
3. Meet IEC60044-1, IEC60044-6 CT/PT standard.
4. Based on an advanced low-frequency testing theory, able to test knee point of the CT test up to 30KV.
5. 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.
6. 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.
7. Easy to carry, instrument weight<9KG.
