MS-601G CT PT Transformer Comprehensive Tester 

1. Comprehensive functionality: It meets the testing requirements for various types of CTs (such as protection, metering, and TP types), including excitation characteristics (i.e., volt-ampere characteristics), transformation ratio, polarity, secondary winding resistance, secondary load, ratio error, and phase angle error.  It can also be used for testing the excitation characteristics, transformation ratio, polarity, secondary winding resistance, ratio error, and phase angle error of various PT electromagnetic units.

2. Automatically provides inflection point voltage and current, 10% (5%) error curve, accuracy limit factor (ALF), instrument security factor (FS), secondary time constant (Ts), remanence coefficient (Kr), saturation and unsaturated inductance, and other CT and PT parameters.
3. The test meets various current transformer standards such as GB1208 (IEC60044-1), GB16847 (IEC60044-6), and GB1207, and automatically selects the appropriate standard for testing based on the type and class of the current transformer.
4. Based on the advanced low-frequency testing principle, it can handle CT tests with inflection points up to 45KV.
5. User-friendly and aesthetically pleasing interface; full graphical interface.
6. The device can store 2000 sets of test data, which are not lost in case of power failure. After the test is completed, the data can be saved to a PC via a USB flash drive, and the software can be used for data analysis and generating a WORD report.
7. Simple and convenient testing: One-button operation completes CT DC resistance, excitation, transformation ratio, and polarity tests.  Except for load testing, all other CT tests use the same wiring method.
8. Easy to carry; the device weighs <9Kg.
