High Frequency Current Transformer (Hfct) Connection - GE Intellix BMT 330 Installation Manual

Figure 5-12: Tightening order
WARNING: Ensure that the Bushing Adaptor has been assembled carefully
with the liquid tight fitting and conduit to form a liquid tight connection.
Water ingress inside the bushing may result in catastrophic failure.
Route all the Bushing Adaptor cables through conduit to the product cabinet. If the
cabling is being routed as part of the pre-installation work, then ensure that the phase is
properly marked on each coaxial cable.

High Frequency Current Transformer (HFCT) Connection

WARNING
from the high voltage neutral bushing (typically identified as H0) directly to
ground. There must not be any open switches between the path to ground
from the neutral bushing while the transformer is energized.
WARNING: If there is a switch on the path to ground from the high voltage
neutral bushing as shown in Figure 5-13, the HFCT must NOT be installed
between the switch and the neutral bushing, because if for any reason the
switch is opened there will no longer be a direct path to ground causing a
potentially hazardous condition.
WARNING: Prior to any test that requires the removal of the transformer
neutral ground, any installed HFCT must first be removed. Replace the
HFCT after the transformer ground has been reconnected.
Preparation of the coaxial cables is outlined in Appendix C.3 and C.6.
