| Transformer Analyzer |
Transformer Analyzer is a new generation of revolutionary CT and PT testing instrument developed on the basis of our company's widely acclaimed and extensively used multifunctional fully automatic comprehensive transformer tester, incorporating extensive user feedback, market research, and in-depth theoretical study. The device employs high-performance DSP and ARM, advanced manufacturing processes, ensuring stable and reliable performance, complete functionality, high automation, and high testing efficiency. It is at the leading level domestically and is a professional testing instrument for transformers in the power industry.
Main Features
1. Comprehensive functions, meeting the testing requirements for various types of CTs (such as protection, metering, TP class) including excitation characteristics (i.e., volt-ampere characteristics), ratio, polarity, secondary winding resistance, secondary burden, ratio error, and phase error, and also applicable for testing various PT electromagnetic units' excitation characteristics, ratio, polarity, secondary winding resistance, ratio error, and phase error.
2. Automatically provides knee point voltage/current, 10% (5%) error curve, accuracy limit factor (ALF), instrument security factor (FS), secondary time constant (Ts), remanence coefficient (Kr), saturated and unsaturated inductance, and other CT and PT parameters.
3. Testing complies with various transformer standards such as GB1208 (IEC60044-1), GB16847 (IEC60044-6), GB1207, etc., and automatically selects the appropriate standard based on transformer type and class.
4. Based on advanced low-frequency method testing principle, capable of handling CT testing with knee point up to 30KV.
5. User-friendly and aesthetically pleasing interface, fully Chinese graphical interface.
6. The device can store 2000 sets of test data, which is not lost upon power failure. After testing, data can be saved to a PC via USB drive for analysis using software, and WORD reports can be generated.
7. Simple and convenient testing, one-key completion of CT DC resistance, excitation, ratio, and polarity tests, and except for burden test, all other CT tests use the same wiring method.
8. Easy to carry, device weight <9Kg.
