S&C’s engineers are committed to making your vision a reality. They understand that during the early stages of a project, requirements may be known only in a general sense, and there may be a variety of ways to fulfill those requirements.
S&C’s has the in-house expertise to develop the optimum solution for your particular needs. Our engineers evaluate options considering trade-offs such as real estate requirements, cost, aesthetics, ease of installation and use, future expandability, ability to interface with existing equipment, and reliability. After your optimum solution has been identified, they’ll work with you throughout the approval process, including your submissions to management, the local zoning board, and others, so that detailed physical and electrical design work can proceed.
Including S&C in the planning phase of a project has proven to reduce costly changes and rework during construction.
Once the requirements of a project have been established, S&C will work with you on the physical design including:
- General Arrangements for Switchyards and Substations
- Site Work – Grading and Drainage Design
- Structures and Foundation Design
- Control House Layouts
- Grounding System Design
- Oil Containment Design
- Conduit/Cable Schedules
- Bill of Materials
S&C’s engineers will apply your designs and standards, or S&C’s own as appropriate, along with applicable national standards and local codes, to develop the physical design package. Reviews and calculations are performed to ensure that standards are met, along with conductor sizing, mechanical loading, structural integrity, and other requirements. The physical design drawings are subjected to S&C’s quality review process to ensure technical accuracy and full compliance with your project requirements.
The result is a total design package that clearly and accurately defines the construction work for your project.
As specialist in electric power switching and protection solutions, S&C is uniquely qualified to provide protection and control design for your substation project. The process begins with the development of a preliminary single-line diagram, indicating the bus arrangement of power transformers, circuit breakers, voltage regulators, disconnect switches, capacitors, instrument transformers, and other 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 creates AC and DC elementary diagrams in accordance with the final relay and instrumentation single-line diagram. These elementary diagrams are subsequently used to create panel layout, connection, and apparatus drawings. The connection drawings are used to create the bill of material and bill of wire (inventory of conductors to be installed, removed, or/and re-terminated) for the project. S&C will then develop appropriate control and protective device settings.
S&C’s expertise in protection and control design ensures that the equipment on your system is properly protected and coordinated.
S&C’s involvement in a project can go beyond the issuance of the final design package. We have the skill and expertise to support the construction process by providing bid packages, guidance at pre-construction meetings and during construction, as well as field observation of construction activities. S&C will also create “as-built” drawings to document the project as actually constructed.
S&C is a committed partner. Our resources, personnel, and expertise are available to you throughout the project lifecycle.
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.
