REQUIREMENTS PRIOR TO COMMISSIONING
The MiCOM P12x relays are fully numerical in their design, implementing all protection and
non-protection functions in software. The MiCOM relays use a high degree of self-checking
and, in the unlikely event of a failure, will give an alarm. As a result of this, the
commissioning test do not need to be as extensive as with non-numerical relays (static or
electromechanical).
To commission MiCOM relays, it is only necessary to verify that the hardware is functioning
correctly and the application-specific software setting have been applied to the MiCOM relay.
It is considered unnecessary to test every function of the relay if the settings have been
verified by one of the following method:
•
Extracting the settings applied to the relay using the appropriate setting software
MiCOM S1 (preferred method)
•
Via the front panel user interface.
REMINDER:
It is not possible to download a new setting software as long as
the programming mode is active.
To confirm that the product is operating correctly once the application-specific settings have
been applied, a test should be performed on a single protection element.
Unless previously agreed to the contrary, the customer will be responsible for determining
the application-specific settings to be applied to the MiCOM relays and for testing of any
scheme logic applied by external wiring.
Blank commissioning test sheets and setting records are provided at the APPENDIX 2 of the
Technical Guide for completion as required.
BEFORE CARRYING OUT ANY WORK ON THE EQUIPMENT, THE
USER SHOULD BE FAMILIAR WITH THE CONTENTS OF THE SAFETY
GUIDE SFTY/4LM/D11 OR LATER ISSUE, OR THE SAFETY AND
TECHNICAL DATA SECTION OF THE TECHNICAL MANUAL AND ALSO
THE RATINGS ON THE EQUIPMENT RATING LABEL.
