Figure 3–8: DETAIL OF INSERTION/EXTRACTION OF COMMUNICATION MODULES
The transformers module with the VTs and CTs is already connected to a female connector screwed to the case
that incorporates shorting bars in the current inputs, so that it can be extracted without the need to short-circuit
the currents externally. It is very important, for safety reasons not to change or swift the terminals for CTs and VTs.
