CTC760E Instrument Transformer Analyzer

FEATURES：

Use direct current method and variable frequency method (low frequency method) testing CT

excitation characteristic below 80KV, working fast.

Use both “voltage method” (through secondary injection) testing current transformer ratio and polarity (include

transformer bushing CTs).

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.

Output up to 200A with external current booster (option)

Test current transformer secondary winding DC resistance.

Test current transformer secondary circuit burden.

Test voltage transformer excitation characteristic, ratio, polarity and secondary winding DC resistance.

Draw the excitation curve and calculating the knee point accordance to IEC60044-1 and IEC60044-6.

Draw 5%, 10% CT error curve.

Measure CT’s ratio error and phase displacement.

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).

Draw current transformer Hysteresis loop curve

Transparent display shows values and curve clearly both indoor and outdoor.

High speed thermal printer can print values and curve.

Check the connecting cable automatically. Wrong connecting warning instructions.

Built-in large memory storage can store 20000 winding test values, loss of power without loss of values.

Use a USB flash drive to transfer the values to PC, and generate report.

Use a USB flash drive to update software.
