Range of measurements
• Ratio and phase accuracy
• Winding resistance
• Excitation characteristics (knee points)
• Composite error (ALF, ALFi, FS, FSi, Vb)
• Burden impedance
• Transient CT classes and parameters (TPS, TPX, TPY and TPZ type CTs)
• Transient dimensioning factor (Ktd)
• If missing/unknown: CT type, class, ratio, knee point, power factor, nominal burden, operating burden, primary and secondary winding resistance
• Remanence and residual magnetism
• Immediate Pass/Fail evaluation
Features:
• Highest measurement accuracy: 0.02 % / 1 min when calibrating on site
• Very small and lightweight (< 8 kg / 17.4 lbs), easy to transport for on-site testing
• Automatic evaluation according to IEC, IEEE and to customized or local/national standards
• Short commissioning times (duration of the automatic test < 1min)
• Excellent workplace safety – Tests run at max. 120 V
• Integration into testing routines using Remote Interface Control
