| Characteristics
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. Test meet IEC60044 GB1208 (-1) GB16847 (IEC60044-6) became etc all kinds of transformer standards, and 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 30KV. Friendly interface beautiful, all Chinese graphic interface 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 9Kg. |
| Specification The instrument is designed for CT and VT testing. It provides an output of 0–180 Vrms, 12 Arms, and a peak current of 18 A.
