Testing IED operation

Preparing for test

Requirements

IED test requirements:
• Calculated settings
• Application configuration diagram
• Signal matrix (SMT) configuration
• Terminal connection diagram
• Technical manual
• Three-phase test equipment
• PCM600
The setting and configuration of the IED must be completed before the testing can
start.
The terminal diagram, available in the technical reference manual, is a general
diagram of the IED.
Note that the same diagram is not always applicable to each specific
delivery (especially for the configuration of all the binary inputs and
outputs).
Therefore, before testing, check that the available terminal diagram corresponds to the
IED.
The technical manual contains application and functionality summaries, function
blocks, logic diagrams, input and output signals, setting parameters and technical data
sorted per function.
The test equipment should be able to provide a three-phase supply of voltages and
currents. The magnitude of voltage and current as well as the phase angle between
voltage and current must be variable. The voltages and currents from the test
equipment must be obtained from the same source and they must have minimal
harmonic content. If the test equipment cannot indicate the phase angle, a separate
phase-angle measuring instrument is necessary.
Prepare the IED for test before testing a particular function. Consider the logic
diagram of the tested protection function when performing the test. All included
functions in the IED are tested according to the corresponding test instructions in this
