Weshine® the CT PT Analyzer invented for CT Tester is a new product created after widely adopting the suggestions of customers and in-depth theoretical research. It is based on the widely acclaimed and applied automatic FA series transformer integrated tester produced by our company. Using high-performance DSP and arm, advanced manufacturing technology ensures stable and reliable product performance, complete functions, high degree of automation, high efficiency, which is at the leading level in China. It is a professional testing equipment industry for instrument transformer testing.
Full-featured, not only satisfy the test requirements of various CTs (include TP class), such as the excitation characteristics (i.e., volt-ampere characteristics), ratio, polarity, secondary winding resistance, secondary burden, ratio error and phase displacement, but can also be used for the tests of various PTs, including excitation characteristics of the electromagnetic unit, ratio, polarity, secondary winding resistance, ratio error and phase displacement.
Automatically give CT, VT parameters, including knee point voltage / current, 10% error curve, the accuracy limit factor (ALF), instrument security factor (FS), the second time constant (Ts), remanence coefficient (Kr), saturated and unsaturated inductance etc.
In accordance with the transformer types and levels of automatic choose which standard test.
Based on advanced principle of low-frequency test method that can meet the CT test on knee voltage up to 30 kV.
The instrument can store 2000 groups of test data that won’t be lost when power off. After test ended, the data can be coped to PC by USB disk for analysis and being transformed into WORD report.
Test is simple and convenient, one-click can complete tests of CT secondary resistance, excitation, ratio and olarity.
Easy to carry, because the weight is less than 9 kg.
