Current Transformer Testing Equipment

Introduction: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.Applications:Tests for current transformer:1) Excitation curve and parameters test2) Turns ratio test3) Ratio and phase error test4) Polarity mark check5) Winding resistance measurement6) Secondary loop burden measurement7) Error line curve test for protection CT8) Transient CT parameters test9) CT nameplate guess10) Saturation hysteresis loop curve measurement
Tests for voltage transformer:1) Turns ratio test2) Ratio error and phase angle error test3) Polarity test4) Secondary burden test5) Winding resistance testFeatures:1. Make evaluation for test results according to selected standards.
2. Make word report for test result.
3. Make word reports one time for multi-group test records on the PC.
4. Calculate the ratio errors and phase angle errors at rated burden and working burden in one time test.
5. Compare excitation curves with saved excitation curves in the same window.Technical index
