Product Details

Product Features

• 1. Comprehensive functions, meeting the test requirements for various types of CTs (such as protection, metering, TP types) 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 including 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. Tests comply with various transformer standards such as GB1208 (IEC60044-1), GB16847 (IEC60044-6), GB1207, and automatically selects the appropriate standard based on the type and class of the transformer.
• 4. Based on advanced low-frequency method testing principle, capable of handling CT tests with knee points up to 30KV.
• 5. User-friendly and aesthetically pleasing interface, full 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 saved to a PC via USB drive for analysis using software, and a WORD report can be generated.
• 7. Simple and convenient testing, one-click completion of CT DC resistance, excitation, ratio, and polarity tests. Except for burden test, all other CT tests use the same wiring method.
• 8. Easy to carry, device weight <9Kg.
