For over 100 years, S&C has specialized in engineering power systems solutions around the world. Through this specialization, we’ve developed the expertise to engineer solutions that help our customers provide safe, reliable, and efficient power. Our services are customized to meet each customer’s technical requirements and budget, while maintaining S&C’s reputation for thoroughness and quality.

S&C has furnished hundreds of electrical and physical design packages in a wide range of complexity and voltage classes. Based on the excellence of our performance, customers around the world continue to trust S&C with their project engineering work year after year.

S&C’s engineers are known for providing practical, cost-effective solutions that exceed customers’ expectations.

S&C’s expertise in protection and control design ensures that the equipment on your system is properly protected and coordinated.

Specializing in electric power switching and protection solutions, S&C is uniquely qualified to provide protection and control designs for your projects. The process begins with development of a preliminary single-line diagram, indicating the bus arrangement of major equipment. The final protection and control design for the substation is presented on a relay and instrumentation single-line diagram that reflects your protection and control philosophy as well as the recommendations of IEEE Standards Collection C37.

S&C will also produce connection drawings that are used to create the bill of materials and bill of wire for the project.

Sophisticated relay logic minimizes interconnection wiring, making for more reliable systems, and allows for future expansion and changes at minimal cost.  With our expertise in the protection of transmission lines, feeders, transformers, and capacitor banks, along with complex control systems, S&C is well qualified to develop the control logic for, and program, relays for a wide variety of applications. We are familiar with the relays from all major manufacturers.

Our proven expertise in relay programming also permits us to offer specialized high-reliability solutions for your distribution system, including our unique High-Speed Fault Clearing Systems, featuring specially configured Vista Underground Distribution Switchgear.

Collecting information from your power system and relaying it back to your operations center is critical. S&C has the in-house capability to provide full SCADA integration services for projects. Our experts can support S&C projects from conceptual design and programming through final commissioning.

We specialize in providing monitoring and controls on a serial- or Ethernet-based network using DNP3.0, MODBUS, and SEL protocols. Our value comes from helping customers set up their substation RTUs to send values and accept control from multiple “masters,” including the substation owner, generator manufacturer, renewable resource supplier, utility, ISO, and control center HMI.

These skills help support S&C’s ability to provide a complete engineering package.
