Modernisation helps maximize performance, improve energy efficiency and cut carbon emissions.
ABB Electrification Service has teamed up with Steel Dynamics Heartland Division (SDI Heartland) to modernize aging substation equipment.
The modernisation helps maximize performance, improve energy efficiency and cut carbon emissions.
SDI Heartland chose ABB to design, build and install new switchgear doors, controls and protection relays at its 18-breaker substation.
Repairing the vintage relays was proving to be a challenge. Replacing them with new technology was essential to ensure reliable power supply to the mill and avoid costly downtime.
Tim Gentry, Business Development Manager, ABB, said: “Servicing aging relays has been an important part of our work at the Heartland operation. So, when it came time to modernize their gear, we were fully aware of the challenges they faced and the importance of delivering a safe, on-time installation.”
SDI Heartland opted for ABB’s Relion 615 series as the new protection relays.
These compact and versatile devices offer protection, control, monitoring and supervision all in one relay. In addition, for increased safety, the relays include arc flash protection, based on optical arc flash detection with fiber-optic light sensors, tripping at arc faults in milliseconds.
To demonstrate the performance and capabilities of the new Relion relays, ABB initially replaced two of the old unreliable relays in SDI Heartland’s substation. The successful smaller-scale project gave SDI Heartland the confidence and conviction to move forward and replace the remaining 16 relays in the medium-voltage line-up.
Beyond a modern set of protection and control relays that help keep the substation operating at optimal conditions, ABB’s Relion 615 series relays also include communications capabilities, enabling SDI Heartland to monitor their main relays and understand what each of their feeders is doing.
“These new Relion relays have a large, user-friendly graphic display and now SDI Heartland’s technicians are able to continuously see the status of their equipment, making it easier for them to get detailed information and make better-informed maintenance decisions to further prevent costly downtime,” said Gentry.
This enhanced communication capability combined with the confidence of modern relay technology will be critical as SDI Heartland grows.
“I’ve always been impressed with ABB and their commitment to quality, safety and service. The experience and expertise of their field engineers are the reason we consistently choose them to help us keep our electrical assets operating as effectively and efficiently as possible,” said Dave Fulford, Engineering and Maintenance Manager, SDI Heartland.
ABB’s modernization services reduce total cost of ownership, maximize return of investment and deliver safer, smarter and more reliable solutions that get the most out of existing assets and typically extend their lifespan for another 20-30 years.
Through product care and servicing to modernizing operations and providing advisory services on the health of electrical distribution systems, ABB helps customers maximize performance, improve energy efficiency and cut carbon emissions.
