Figure 11:Correct distribution of conductors�
The inadequate arrangement of the conductors, as shown in
Figure 12
, as well as not
following the recommendations indicated in
Figure 13
, can cause the transformer
to lose its measurement efficiency and residual current protection. Unexpected
disconnections may occur in the installation if the WGC is associated to a differential
relay that actuates the circuit breaker.
