I.Features
Safety regulations for CT/PT Analyzer application
All technical index should keep in work condition before testing with Analyzer.
Please follow associated international standards in a special application.
Forbid high voltage or high current connected to CT/PT Analyzer directly.
All tests need to follow procedure in user manual.
It is forbid to open the box of CT/PT Analyzer. Otherwise, the quality assurance will be invalid.
It is forbid to update or extend the tester without manufacturer authorization.
Please use the original accessories for Analyzer.
It is forbid to cut off test connection before LED indicator light is OFF.
Please connect Analyzer to ground with grounding cable in no laboratory application.
Please confirm that one terminal of sample CT primary connected to ground.
Do not run Analyzer in extreme moist condition.
Please confirm that all terminals connected to Analyzer have no voltage. All voltage outputs are from CT/PT Analyzer.
Please confirm that voltage had been injected to CT secondary winding in CT test. Otherwise, CT/PT Analyzer will be damaged possibly.
Please confirm that voltage had been injected to PT primary winding in PT ratio test. Otherwise, CT/PT Analyzer will be damaged possibly.
The ratio error and phase angle error test is valid for electromagnetic voltage transformer only. It can not applied in CVT test.
