  • Current Transformer Tester The tester delivers up to 1000 Volts at 60 Hertz, with a maximum current of 1.00 Amp (intermittent). If the 1.00 Amp capability is enough amplitude to saturate the CT under test, the tester can also be used to degauss the CT from a previous saturation abnormality. Some users employ forced air cooling on the tester’s components, thereby allowing it to continuously deliver a 0.5 Amp output.
