Project Description
Product Features:
The device can store 2000 groups of test data, which will not be lost after power failure. After the test is completed, save it in the PC with a U disk, analyze the data with the software, and generate a WORD report
The test is simple and convenient. The direct resistance, excitation, transformation ratio and polarity test of CT can be completed with one key. In addition to the load test, all other CT tests use the same wiring method.
Easy to carry, device weight <9Kg
Based on the advanced low-frequency method test principle, it can handle the CT test with the inflection point up to 45KV
The device can store 2000 groups of test data, which will not be lost after power failure. After the test is completed, save it in the PC with a U disk, analyze the data with the software, and generate a WORD report.
Product nicknames: PT volt-ampere characteristic tester, transformer volt-ampere characteristic tester, CT volt-ampere characteristic tester, CT volt-ampere characteristic tester, PT volt-ampere characteristic tester, transformer volt-ampere characteristic tester, Volt-ampere characteristic transformation ratio polarity comprehensive tester, volt-ampere characteristic tester, volt-ampere characteristic comprehensive tester, LTFA-F volt-ampere characteristic tester, CTPT characteristic comprehensive tester, transformer comprehensive tester.It also belong to power transformer testing.
The device uses high-performance DSP and ARM, and advanced manufacturing technology to ensure stable and reliable product performance, complete functions, high automation, high test efficiency, and a leading level in the country. It is a professional test instrument for transformers in the power industry.
Comprehensive functions, which not only meet the excitation characteristics (ie volt-ampere characteristics), transformation ratio, polarity, secondary winding resistance, secondary load, ratio difference, and angle difference of various CTs (such as protection, measurement, TP) It can also be used to test the excitation characteristics, transformation ratio, polarity, secondary winding resistance, ratio difference and angle difference of various PT electromagnetic units.
The inflection point voltage/current, 10% (5%) error curve, accuracy limit factor (ALF), instrument security factor (FS), quadratic time constant (Ts), remanence factor (Kr), saturation and no CT and PT parameters such as saturation inductance.
The test meets various transformer standards such as GB1208 (IEC60044-1), GB16847 (IEC60044-6), GB1207, etc., and automatically selects which standard for testing according to the type and level of the transformer
