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 value 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.
10.4.7.3
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 =
UseFunctionMode.

Setting StartMode is added to choose how retrip and backup trip timers can run. The
choices are; to run the timers by external start signal which is latched, to follow the
external start signal only or to follow the external start signal and the selected
FunctionMode.
