Transformer Analyzer
Darui Electric recommends
Transformer Analyzer is a new generation of revolutionary CT and PT testing instrument developed based on our company's widely acclaimed and extensively used multifunctional fully automatic comprehensive transformer tester, incorporating extensive user feedback, market research, and in-depth theoretical studies. The device employs high-performance DSP and ARM, advanced manufacturing processes, ensuring stable and reliable performance, complete functionality, high automation, and high testing efficiency, leading domestically and serving as 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, as well as for various types of 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 curves, 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 GB1208 (IEC60044-1), GB16847 (IEC60044-6), GB1207, and other transformer standards, 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 points 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 on power failure. After testing, data can be transferred to a PC via USB drive for analysis using software and generating WORD reports.
7. Simple and convenient testing, one-click 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.
