Section 13 Verifying settings by secondary injection
About this chapter
This chapter describes how to verify that protection functions operate correctly and
according to their settings. It is preferable that only the tested function is in operation.
13.1 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.
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.
