HV CT PT Analyzer GF1061 Class 0.05 Current Transformer Testing Instrument
GF1061 portable CT PT analyzer is mainly used for field or lab testing, it can finish the measurements (M) and protection (P) class CT, PT and TYP class CT. Adopt 7 inch touch TFT LCD, self-equipped mini type printer supporting field printing; supporting to use USB flash disk to dump data. The CT PT Analyzer is the most complete and easy-to-use testing system for protection and metering CTs according to IEEE and IEC standards.
The CT Analyzer is the most complete and easy-to-use test system for protection and metering CTs according to IEEE and IEC standards. It combines the highest safety standards with CT test and assessment features. The CT Analyzer approach.
Before starting to work, clearly establish the responsibilities. Personnel receiving training, instructions, directions, or education on the CT Analyzer must be under constant supervision of an experienced operator while working with the equipment. The operator is responsible for the safety requirements during the whole test.CT Kneepoints up to 80kV CT grouped testing includes Demagnetization, Knee Points, Ratios, Saturation Curves, Winding Resistances, Polarities and Phase Deviation (on all taps of multi-ratio CTs) VT testing including Demagnetization, Ratio, Winding Resistance, Polarity and Phase Deviation.
