Identifying IED application problems

• Check that the function is on.
• Check the blocking.
• Check the mode.
• Check the measurement value.
• Check the connection to trip and disturbance recorder functions.
• Check the channel settings.
5.4.4.1 Checking of the power supply
Check that the auxiliary supply voltage remains within the permissible input voltage
range under all operating conditions. Check that the polarity is correct before
powering the IED.
5.4.4.2 Sample data interruptions
Occasionally IEDs can receive corrupted or faulty measurement data during
runtime. In these cases the operation system halts the corresponding application
execution until correct data is received. In case of permanent faults, the
measurement chain should be checked to remove the origin of the faulty
measurement data.
