How to test semi insulated voltage transformers using a AC Resonant Test System with Variable Frequency
The AC Resonant Test System with Variable Frequency is a device used to test the insulation performance of electrical equipment,and can be used to test the insulation performance of semi insulated voltage transformers.When testing semi insulated voltage transformers,the following steps can be followed for testing:
1.Wiring:Connect the semi insulated voltage transformer to the series resonant withstand voltage test device,ensuring that the connection is correct and secure.
2.Set testing parameters:Based on the rated voltage and testing requirements of the semi insulated voltage transformer,set the testing parameters of the series resonance withstand voltage test device,including testing voltage,testing time,etc.
3.Conduct testing:Start the series resonance withstand voltage test device,let it output the test voltage,and test the semi insulated voltage transformer.During the testing process,monitor changes in parameters such as test voltage and insulation resistance.
4.Analyze test results:Based on the test results,determine whether the insulation performance of the semi insulated voltage transformer meets the requirements.If the test results are normal,it indicates that the insulation performance of the semi insulated voltage transformer is good;If the test results are abnormal,further inspection and handling are required.
Through the above steps,a series resonance withstand voltage test device can be used to test the insulation performance of a semi insulated voltage transformer,ensuring its safe and reliable operation.
