7.2 Configuration Menu Overview
The configuration menu regroups all the parameters of the CTT instrument along
with its data exportation and file management features.
7.2.1 Menu - Operation Mode
The CTTx5 and CTTx2 can be configured in one of the three available modes:
• Manual Mode: Helpful for quick CT test that doesn't require to be saved,
exported or printed. The manual mode is also very useful for CT diagnostic
purposes. Refer to section 8.1 for more information on how to operate the
manual mode.
• Automatic Mode: Prior going on site, the operator has the possibility to create
complete test plans for every CT configuration. A test plan can then be used to
test same-spec CTs found in a power transformer for example. When selected,
the automatic mode will perform all selected tests (insulation, winding
resistance, saturation curves, ratio, polarity and phase shift) on a given CT.
The operator can then annotate the CT information and save the report to
memory. Refer to section 8.2 for more information on how to operate the
automatic mode.
• Burden Mode: The burden mode allows to measure the impedance of the
circuit normally connected to the CT's secondary. Refer
to section 8.3 for more information on how to operate
the burden mode.
