Verifying correct terminal-phase connections of all incoming feeders
☒ Use phase comparison test unit according to IEC 61243-5 or VDE 0682-415.
☒ The panel of the incoming feeder to be tested must be in OPEN position.
☒ The opposite substation must be de-earthed and live.
1. Remove the covers of the capacitive test sockets from phase L1 on the incoming feeder to be
tested and on an already energized incoming feeder.
✓ The plug-in sockets of the capacitive voltage detecting system on phase L1 are accessible.
2. Plug the measuring cables of the phase comparison test unit into the plug-in sockets of the
capacitive voltage detecting system according to the instruction manual.
3. Perform phase comparison according to the operating instructions of the phase comparison
test unit and read the indication.
4. Remove the measuring cables from the plug-in sockets.
5. Refit the covers of the capacitive test sockets on both incoming feeders.
6. Perform phase comparison for the phases L2 and L3 in the same way.
✓ If the phase comparison test unit has shown coincidence on all 3 phases, the phase
sequence of the tested incoming feeder is correct.
✓
The incoming feeder can be energized.
Applying voltage to the busbar
If the phase sequence of all incoming feeders is correct, the incoming feeders can be connected
to the busbar:
✓
The busbar of the switchgear is live.
Energizing consumer feeders
When all incoming feeders are connected to the busbar:
1. One after the other, energize all consumer feeders with connected consumers.
✓
When all consumer feeders are energized, the switchgear is completely in operation.
8.8 After commissioning
▪ Observe the locally applicable specifications for prevention of accidents.
▪ If after commissioning further work is required in the area of the switchgear, install warning
signs at the switchgear.
Access for working in the area of the switchgear must only be granted to the following persons:
▪ Electricians and persons who have been properly instructed in electrical engineering
▪ Persons under the supervision of electricians and persons who have been properly instructed
in electrical engineering
Documenting the commissioning
1. Document any modification due to installation.
2. Document the modifications in the circuit diagram.
3. Send the documented modifications to the competent contact partner of Siemens AG.
