High Quality Hv CT PT Analyzer Testing Instrument
CT test items:
1. The excitation characteristic and parameters of the current transformer need to be tested.
2. The turns ratio between the primary and secondary windings needs to be measured.
3. The ratio and phase angle errors must be checked.
4. The polarity markings should be verified.
5. The resistance of the windings should be measured.
6. The burden of the secondary loop needs to be determined.
7. An error line curve test for the protection current transformer is required.
8. The transient parameters of the current transformer must be measured.
9. An attempt should be made to deduce the nameplate specifications of the current transformer.
10.The saturation hysteresis loop curve of the current transformer needs to be plotted through measurements.
PT test items:
1. The ratio between the number of turns in the primary and secondary windings needs to be determined through measurement.
2. Testing is required to check for any ratio error and phase displacement error.
3. A test must be conducted to ensure the polarity markings are correct.
4. A test should be performed to determine the loading characteristics of the secondary winding.
5. The resistance of the windings should be measured through testing.
Usages of CT/ PT Analyzer:
1. The nameplate information of the current transformer should be verified.
2. The electrical parameters of the current transformer need to be evaluated under working load conditions.
3. An analysis of the transient performance parameters of the current transformer is required.
4. Calibration of the ratio and phase error of the current transformer is needed.
5. The current transformer needs to undergo standard tests to ensure proper functioning.
