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.
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.
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.
