The IED does not restart after reconfiguring IEC61850 (regardless of
whether the protocol is enabled or disabled).
Be sure to set the correct technical key in both the IED and PCM600
to prevent writing an application configuration to a wrong IED.
See the engineering manual for information on how to create or
modify an application configuration and how to write to the IED.
3.7 Checking CT circuits
Check that the wiring is in strict accordance with the supplied
connection diagram.
• Primary injection test to verify the current ratio of the CT, the correct wiring up
to the protection IED and correct phase sequence connection (that is L1, L2, L3.)
• CT secondary loop resistance measurement to confirm that the current
transformer secondary loop DC resistance is within specification and that there
are no high resistance joints in the CT winding or wiring.
• Earthing check of the individual CT secondary circuits to verify that each three-
phase set of main CTs is properly connected to the station earth and only at one
electrical point.
• Insulation resistance check.
CT and VT connectors are pre-coded, and the CT and VT connector
markings are different. For more information, see the installation
manual.
Both the primary and the secondary sides must be disconnected from
the line and the IED when plotting the excitation characteristics.
3.8 Checking VT circuits
Check that the wiring is in strict accordance with the supplied connection diagram.
