Functional Features
※ Comprehensive functions, meeting the test requirements for various 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 PT electromagnetic units including excitation characteristics, ratio, polarity, secondary winding resistance, ratio error, and phase error.
※ 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.
※ Based on advanced low-frequency method testing principle, capable of handling CT tests with knee point up to 30kV.
※ The device can store 2000 sets of test data, which will not be lost upon power failure. After the test, use a USB drive to transfer data to a PC, perform data analysis with software, and generate a WORD report.
