Section 5
Testing IED operation
36
During testing, observe that the right testing method, that corresponds to the actual
parameters set in the activated parameter setting group, is used.
In the local HMI the sensitive directional earth fault protection SDEPSDE parameter
group 4 is active indicated by the * next to #4 and the test of the SDEPSDE must be
performed according to the instructions given for the setting OpMode and setting
value 3I03U0cosfi.
Set and configure the function(s) before testing. Most functions are highly flexible and
permit a choice of functional and tripping modes. The various modes are checked at
the factory as part of the design verification. In certain cases, only modes with a high
probability of coming into operation need to be checked when commissioned to verify
the configuration and settings.
Requirements for testing the function.
• Calculated settings
• Valid configuration diagram for the IED
• Valid terminal diagram for the IED
• Technical manual
• Three-phase test equipment
Content of the technical manual.
• Application and functionality summaries
• Function blocks
• Logic diagrams
• Input and output signals
• A list of setting parameters
• Technical data for the function
The test equipment should be able to provide a three-phase supply of currents and
three-phase voltage. The magnitude and angle of currents (and voltages) should be
possible to vary. Check that 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)
• Using the online mode in the PCM600 configuration software
Do not switch off the auxiliary power supply to the IED before
changes, for example, setting parameter or local/remote control state
changes are saved.
A mechanism for limiting the number of writings per time period is included in the
IED to prevent the flash memory to be worn out due to too many writings. As a
