Potential Current Transformer Analyzer CT PT Testing Equipment

Product Description

Potential Current Transformer Analyzer ct pt testing equipment

I. Summary:

CT PT analyzer 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.

II. Applications:

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) Winding 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) Ratio error and phase angle error test
3) Polarity test
4) Secondary burden test
5) Winding resistance test


III. Features:

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.
