WARNING: Prior to any test that requires the removal of the transformer
neutral ground, any installed HFCT must first be removed. Replace the
Neutral HFCT after the transformer ground has been reconnected.
Preparation of the coaxial cables is outlined in Section 9.4.1.1.3 and 9.4.1.1.6.
Figure 9-13: HFCT cannot be installed if a switch is on cable from the Neutral Bushing to ground
To minimise noise, the HFCT should be installed as close to the High Voltage Neutral
bushing as possible provided there is no switch on path to ground as per the warning
above. Figure 9-14 and Figure 9-15 show the correct installation of the HFCT.
