ABB REL650 - Identifying the Function to Test in the Technical Reference Manual; Impedance Protection; Distance Protection Zones, Quadrilateral and Mho Characteristic ZMFPDIS

When the IED is brought into normal service it is recommended to delete all events
resulting from commissioning tests to avoid confusion in future fault analysis. All
events in the IED can be cleared in the local HMI under Main Menu//Clear/Clear
internal event list or Main menu/Clear/Clear process event list. It is not
possible to clear the event lists from PCM600.
When testing binary inputs, the event list (EL) might be used instead. No uploading
or analyzing of registrations is then needed since the event list keeps running,
independent of start of disturbance registration.

Use the technical manual to identify function blocks, logic diagrams, input and
output signals, setting parameters and technical data.

Prepare the IED for verification of settings outlined in section
"Requirements" and
section "Preparing for test" in this chapter.
Measure operating characteristics during constant current conditions. Keep the
measured current as close as possible to its rated value or lower. But make sure it is
higher than the set minimum operating current.
Ensure that the maximum continuous current to the IED does not exceed four times
its rated value, if the measurement of the operating characteristics runs under
constant voltage conditions.
The test procedure has to take into consideration that the shaped load encroachment
characteristic is active. It is therefore necessary to check the setting. To verify the
settings with the shaped load encroachment characteristic the test should be carried
out according to figures
12 and 13 and tables 15 and 16. In cases where the load
encroachment characteristic is activated tests according to the adjusted figures
should be carried out.
To verify the settings for the operating points according to the following fault types
should be tested:
• One phase-to-phase fault
• One phase-to-earth fault
