Distributed busbar protection REB500
Section 2 Commissioning
2.1 Preconditions
It is assumed that the REB500 protection system is already installed and all input
and output signals that have been configured are also wired and the optical fiber
cables are run and tested.
It must also be assumed that the busbars or sections of them are in operation and
that circuit-breakers and isolators are in the process of being installed or
maintained.
The commissioning engineer requires the operating instructions and the station
diagrams prepared by the respective engineering department.
The protection system may only be commissioned by trained commissioning
personnel.
The greatest care must be taken when testing a busbar protection
system on busbars in operation, as the consequences of unexpected
operation in due process of the commissioning can be extremely
serious.
The REB500 protection system is equipped with an extensive,
continuous self-supervision and diagnosis feature. All functions are
constantly monitored by the system software. The overall system
has been extensively tested by ABB before releasing the product.
It is therefore not necessary to re-test the internal protection
algorithm by secondary injection.
This manual is therefore restricted to verifying the correct
connection to the primary process.
