● Portable design with light weight of 8kg, suitable for field test of electric power system, manufacturing factory of current transformer or laboratory to use.
● High measurement accuracy, resistance accuracy is 0.1%+1mΩ, phase accuracy±0.05 degree, variable accuracy is ±0.1% (1-5000 ), variable accuracy is ±0.2%(5000-10000).
● It can test current transformer according to IEC60044-1, IEC60044-6, IEC61869-2 and ANSI30/45 standard etc.
● Complete measurement function, it can test all type current transformer for secondary overload, secondary loop resistance, excitation characteristic, transient characteristic, ratio difference, angle difference and polarity. It can also test exact limit coefficient(ALF), device security coefficient(FS), secondary time constant(Ts), remanence coefficient(Kr), transient area coefficient(Ktd), inflexion voltage, current, level, saturation inductance, un-saturation inductance, 5% 10% error curve, of current transformer, hysteresis loop for current transformer, and evaluate test result according to defined standard.
● PT Test As for those inductive PT based on the definition of GB1207-2006(IEC60044-2), KT210 CT/PT Analyzer can also test them. KT210 CT/PT Analyzer can do variable ratio, polarity and secondary winding excitation test of inductive PT.
