Product Description

      GDVA-404   IEC60044 Power Transformer CT Test 


Product Description

 I Power Transformer CT Test Introduction 

This IEC60044 Power Transformer CT Test  is performing excitation, ratio and phase error, polarity, secondary loop burden and coil resistance on current and voltage transformer. The instrument provides fully automatic testing and calibration for all types of low leakage flux current transformer and inductive voltage transformer. The maximum knee point voltage of sample CT could be reached 8.4kv. 

The standards support by IEC60044 Power Transformer CT Test include IEC60044-1, IEC60044-2, IEC60044-6 and C57.13


II Power Transformer CT Test Application 


Tests for current transformer:
1)Excitation curve and parameters test
2)Turns ratio test
3)Ratio and phase error test
4)Polarity mark check
5)Coil resistance measurement
6)Secondary loop burden measurement
7)Error line curve test for protection CT
8)Transient CT parameters test
9)CT nameplate guess
10)Saturation hysteresis loop curve measurement


Tests for voltage transformer:
1)Turns ratio test
2)Polarity test
3) Secondary burden test
4) Coil resistance test




Applications for Power Transformer CT Test :
1) CT nameplate check
2) CT parameters check in work burden
3) CT transient parameters analysis
4) CT ratio and phase error calibration
5) PT routine test
