How CT Analyzer Works: Injects low-test signals into secondary side of CT. Determines equivalent circuit parameters, identifies all relevant CT performance parameters. Displays all relevant parameters of the CT and its accuracy at different currents and burdens. Evaluates CT according to selected standard. Determines unknown CT nameplate parameters. Demagnetizes CT after test. Range of measurements: Ratio and phase accuracy; winding resistance; excitation characteristics (knee points); composite error (ALF, ALFi, FS, FSi, Vb); burden impedance; transient classes/parameters (TPS, TPX, TPY and TPZ type CTs); transient dimensioning factor (Ktd); if missing/unknown: type, class, ratio knee point power factor nominal burden operating burden primary winding resistance secondary winding resistance remanence residual magnetism immediate good/bad evaluation.
