CTC760E CT Analyzer (Variable frequency method)
CTC760E Instrument transformer analyzer can carry out a series of standard tests quickly, such as determining the magnetization characteristic, saturation behavior (ALF/FS), transformation ratio and its accuracy, polarity, load, winding resistance, or remanence. Tests are performed in accordance with standards: IEC60044-1, IEC60044-6, IEC 61869, ANSI/IEEE C57.13.1.
描述
l Use direct current method and variable frequency method (low frequency method) testing CT
excitation characteristic below 80KV, working fast.
l Use both “voltage method” (through secondary injection) testing current transformer ratio and polarity (include
transformer bushing CTs).
l Built-in power supply has an output current mode. Can use current method test current transformer ratio, polarity and check the integrity of the CT secondary circuit.
l Output up to 200A with external current booster (option)
l Test current transformer secondary winding DC resistance.
l Test current transformer secondary circuit burden.
l Test voltage transformer excitation characteristic, ratio, polarity and secondary winding DC resistance.
l Draw the excitation curve and calculating the knee point accordance to IEC60044-1 and IEC60044-6.
l Draw 5%, 10% CT error curve.
l Measure CT’s ratio error and phase displacement.
l Measure CT’s remanence factor (Kr), magnetizing inductance (Lm), secondary loop time constant (Ts), transient dimensioning factor (Ktd), peak instantaneous error (PIE), accuracy limit factor (ALF), instrument security factor (FS).
l Draw current transformer Hysteresis loop curve
l Transparent display shows values and curve clearly both indoor and outdoor.
l High speed thermal printer can print values and curve.
l Check the connecting cable automatically. Wrong connecting warning instructions.
l Built-in large memory storage can store 20000 winding test values, loss of power without loss of values.
l Use a USB flash drive to transfer the values to PC, and generate report.
l Use a USB flash drive to update software.
