Commissioning manual
Testing functionality by secondary injection
• Calculated settings
• Valid configuration diagram for the IED
• Valid terminal diagram for the IED
• Technical reference manual
• Single phase test equipment
The technical reference manual contains application and functionality summaries,
function blocks, logic diagrams, input and output signals, a list of setting
parameters and technical data for the function.
The test equipment should be able to provide a single phase supply of currents. The
magnitude of currents should be possible to vary.
Make sure the IED is prepared for test before starting the test session. Consider the
logic diagram of the function when performing the test. The response from a test
can be viewed in different ways:
• Binary output signals
• Service values in the local HMI (logical signal or phasors)
• A PC with PCM600 (configuration software) in debug mode
Checking the phase current operate value IP>
Procedure
1. Apply the fault condition, including START of CCSRBRF, with a current
below set IP>.
2. Repeat the fault condition and increase the current in steps until a trip occurs.
3. Compare the result with the set IP>.
4. Disconnect the AC and start input signals.
Note! If "No CBPos Check" or "Retrip off" is set, only back-
up trip can be used to check set IP>.

Checking the re-trip and back-up times

The check of the set times can be made in connection with the check of operate
values above. Choose the applicable function and trip mode, such as FunctMode =
Current and RetripMode = CB Pos Check .
