Current Transformer Test Set

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
