The Spring Festival of 2022 has just passed, and Wuhan Security Inspection Electric has welcomed a good start to the new year. In early February of this year, the business order volume increased significantly compared to the same period in previous years. The orders include Jiangxi, Baoding, Nanjing, Wuhan, overseas, etc., all of which are our company's AJ708 variable frequency transformer comprehensive characteristic tester.
This device is a new generation of current and voltage transformer testing instrument developed by Security Electrical after extensive listening to user opinions, extensive market research, and in-depth theoretical research. The device adopts high-performance DSP and ARM, advanced manufacturing technology, ensuring stable and reliable product performance, complete functions, high degree of automation, high testing efficiency, and is at the leading level in China. It is a professional testing instrument for transformers in the power industry.
The AJ708 variable frequency transformer comprehensive characteristic tester has:
1. Fully functional, it not only meets the testing requirements for excitation characteristics (i.e. volt ampere characteristics), transformation ratio, polarity, secondary winding resistance, secondary load, ratio difference, and angle difference of various CTs (such as protection, metering, TP), but also can be used for testing excitation characteristics, transformation ratio, polarity, secondary winding resistance, ratio difference, and angle difference of various PT electromagnetic units.
2. Automatically provide CT and PT parameters such as inflection point voltage/current, 10% (5%) error curve, accuracy limit factor (ALF), instrument safety factor (FS), quadratic time constant (Ts), remanence coefficient (Kr), saturated and unsaturated inductance.
3. The test meets various transformer standards such as GB1208 (IEC60044-1), GB16847 (IEC60044-6), GB1207, etc. Based on advanced low-frequency testing principles, it can cope with CT testing with inflection points up to 45KV.
5. The interface is friendly and beautiful, with a fully Chinese graphical interface.
6. The device can store 2000 sets of test data without loss in case of power failure. After the experiment is completed, use a USB flash drive to store the data on the PC and use software for data analysis. The testing is simple and convenient, with one click completion of CT direct resistance, excitation, transformation ratio, and polarity testing. In addition to load testing, all other CT tests use the same wiring method.
8. Easy to carry, device weight<9Kg.
