Verifying settings by secondary

1 Overview
IED test requirements:
• Calculated settings
• Application configuration diagram
• Signal matrix (SMT) configuration
• Terminal diagram
• Technical reference 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. but 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 reference 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 and the test instructions are therefore presented in alpha-
betical order. 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 in the local HMI (logical signals or phasors)
• A PC with PCM600 application configuration software in debug mode
All setting groups that are used should be tested.
Note!
This IED is designed for a maximum continuous current of four times the rated current.
