A5.1.4 Connection of the primary main cables and
the voltage transformers:
Due to the limited mounting space inside the cable
compartment the primary cables and the voltage
transformers are connected with connectors make Tyco
type RSTI 58. The connectors and cables for the voltage
transformers are pretested and preassembled on the
cable cones of the circuit-breaker. (panel 3).
Parallel on these preassembled connectors the
connectors type RSTI CC58 for the primary main cables
can be mounted at site.
A5.1.5 Removing/remounting the current
transformers
For easy connection of the primary cables the current
transformers in the cable compartment can be removed
and remounted.
Removing when the primary cables are mounted:
1. Open the cable compartment according to the
standard instructions.
2. Remove the current transformers for protection (A)
by removing the two bolts on the front (B).
The secondary wiring does not need to be
disconnected.
3. Behind these current transformers a mounting plate
fixed with bolts ( C) becomes visible. Remove these
bolts and remove the mounting plate.
4. The current transformers for metering (D) can now be
lifted and removed, also remove the tywrap from the
secondary wiring. The secondary wiring does not
need to be disconnected.
Remounting:
Lead the primary cables through the current transformers
and remount the current transformers as described above.
REMARK
After remounting the current transformers the
earth screen connections of the primary cables
must be connected to earth via the premounted
earth wires (F). In this case any earth current
through these connections will not influence the
metering results
