I. Features

Safety regulations for transformer tester 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.
