Testing IED operation

Preparing for test
IP336-1 v1
11.1.1
Requirements
M11740-2 v8
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 chapter. The functions can be
tested in any order according to user preferences. Only the functions that are used (
Operation
is set to
On) should be tested.
The response from a test can be viewed in different ways:
•
Binary outputs signals
•
Service values on the local HMI (logical signals or phasors)
•
A PC with PCM600 application configuration software in work online mode
All setting groups that are used should be tested.
