Ground Fault

The EntelliGuard TU Trip Unit provides a non-core CT input
for zero sequence or residual summation current. The
expected ratio is 1A = 100%.
Neutral Rogowski
The Neutral Rogoswki CT's are used to measure the Neutral
Current and is required when Internal Ground Fault is
selected on the trip unit. There are two types available:
1. Encased with Terminal Screws: The Rogowski coil is
encased with two terminal screws. No additional
mounting hardware is required as the encasing is
molded to the mounting dimensions. Table 4.30
2. Loose Rogowski Coil with separate mounting
hardware: The coil and mounting hardware are
separate. The coil comes with the two wire leads
for connection to a terminal block. Table 4.30a
