Section 10 Testing IED operation
10.1 Preparing for test
10.1.1 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.
