Relaying Current Transformer Analyser

• Measures Ratio, Excitation Characteristics, Polarity, Winding Resistance, Remanance, and Insulation Resistance of secondary winding.
• Determines Composite Error.
• Used to test un-mounted CTs or CTs that are mounted but isolated inside the power system equipment.
• Conducts a whole series of tests automatically, thus speeding up the time to commission CTs and relaying systems.
• Battery powered test set - light weight & fully portable.
• Provides a graphical presentation of the CT excitation characteristics.
• Determines the IEC 10/50 knee point and the point of maximum permeability, ANSI 45 degree Slope Point.
• Detects shorted turns or insulation problems within the test CT, thus avoiding commissioning of faulty equipment.
