Transformer module for AC analog input (VCT)
The transformer module (VCT) of the IED is used to acquire the power system quantities. A
safety feature is available such that all of the VCT current inputs are shorted when a VCT
module is removed from the IED case. Note also that all of the voltage inputs are disconnected.
However, the user should make short circuit all AC current inputs and disconnect all AC
voltage inputs.
Note: We represent respective input signals at the “AC analog input (VCT)” as “Channel
numbers (Ch*)” when settings as to the ratio and others are required. The figure
below shows the operation screen for the AC analog input, which we shall discuss
later. The term “AI#1” in the below figure represents the VC alpha-numeric
references discussed in the preceding section.
The blow figures exemplify the ratio settings for respective channels on the VCT. For more
information about the operation of LCD screen, see chapter
User interface
. The user can also
set them using GR-TIMES (see chapter
Engineering tool
).
