Main features
1. Full function, which not only satisfies the excitation characteristics (ie volt-ampere characteristics), turns ratio, polarity, secondary winding resistance, secondary load, ratio difference of various types of CT (eg protection, metering, TP) Angle and other test requirements, can also be used for various types of PT electromagnetic unit excitation characteristics, turns ratio, polarity, secondary winding resistance, ratio difference and other tests.
2. On-site verification of current transformers does not require standard current transformers, current regulators, load boxes, voltage regulation control boxes and high-current wires. It uses extremely simple test wiring and operation to achieve current transformer verification, which greatly reduces the work. The strength and work efficiency are improved, and is facilitatedthe on-site verification of the transformer.
3. It can accurately measure the turns ratio and angular difference, the maximum allowable error of the difference is ±0.1%, and the maximum allowable error of the angular difference is ±5min. It can carry out the field test of the 0.2S class current transformer, and the ratio measurement range is 1~40000.With the special booster of our company, it can output 180A current, which is convenient for on-site flow test.
4. Test CT/PT volt-ampere characteristic curve and 10% error curve based on advanced frequency conversion method, output AC voltage of only 180V and AC current of 12Arms (36A peak), but can cope with CT test with inflection point up to 60KV.
5. Automatically give Inflection point voltage/current, 10% (5%) error curve, accuracy limit coefficient (ALF), instrument security factor (FS), quadratic time constant (Ts), remanence coefficient (Kr), saturation and unsaturated CT/ PT parameters.
6. Test to meet GB1208 (IEC60044-1), GB16847 (IEC60044-6), GB1207 and other types of transformer standards, and automatically select which standard according to the type and level of transformers for testing.
7. The test is simple and convenient, one-button CT straight resistance, excitation, turns ratio and polarity test. TheCT and other tests can be done only use the same wiring, except the load test.
8. Chinese/English dynamic graphic interface, can complete the wiring, set parameters even no need to read the manual: dynamic display parameter setting, automatically display its related parameters according to the currently selected test items; dynamic display help wiring diagram, the corresponding wiring diagram is displayedaccording to the currently selected test items.
9.5.7-inch graphic transflective LCD, clear to see even in the sun.
10. It is operated by rotating optical mouse, which is easy to operate, fast and convenient, and easy to learn.
11. The panel comes with a printer that automatically prints the test report.
12. The device can store 1000 sets of test data, and will not lose when the power is off.
