Wesfarmers Curragh - CHPP Incomer Upgrade and Arc Flash Study
MRM Engineering was engaged by Wesfarmers Curragh to manage the upgrade of six 2500A incomer circuit breakers in the Coal Preparation Plant Switchboards. MRM completed the installation design and busbar measurements, revised the electrical schematics and prepared the scope of work for the upgrade.
As an integral part of the upgrade, MRM Engineering completed an arc flash study on the switchboards in the Coal Preparation Plant at Wesfarmers Curragh. MRM used SKM© Power Tools software to complete the assessment of the arc flash study in accordance with NFPA 70E 2012 Annex D.7 IEEE1584 method for determining arc flash boundaries. Electrical drawings of the electrical installation were completed with the requisite arc flash study details.
