CT PT Analyzer HYVA-405
HYVA-405 is used to measure all kinds of current transformer and voltage transformer. It can calculate the ratio errors and phase angle errors of current transformer and voltage transformer at rated burden and working burden in one time test. The tester can automatically evaluate the test results according to the selected standard to determine whether the transformer is qualified.
Tests for Current Transformer:
1)Ratio error and phase error test for all CTs
2)Excitation curve and knee point test for all CTs
3)Instrument factor FS test of measurement CTs
4)Accuracy limit factor ALF measurement of protection CTs
5)CT Winding resistance measurement
6)Short current factor Kssc and dimension factor Ktd test for transient protection CTs
7)CT polarity test
8)CT secondary burden test
9)CT nameplate deduce
10) Test multi taps CT with switch box
11) Test bush CT inside body of power transformer
Tests for Voltage Transformer:
1) Ratio error and phase error test of VT
2) Excitation curve test of VT
3) VT Secondary burden test
4) Winding resistance test of VT primary and secondary
5) VT and CVT ratio error test with 4KV voltage booster
6) VT induce voltage withstand test
