SEL-7200

Configure-to-Order (CTO) Panels and Retrofit Plates

Increased quality, faster lead times, and reduced total cost of ownership.

The SEL-7200 CTO family of panels and retrofit plates provides predesigned, advanced solutions for protection, control, automation, communications, and cybersecurity in different substation applications.

  • A consistent, methodical design and manufacturing approach offers higher quality, reliability, and performance than traditional custom panels.
  • Predesigned and validated settings for application modules speed up deployment while guaranteeing functionality.
  • Achieve up to a 40 percent savings in total cost of ownership versus a comparable custom panel.
  • CTO panels and plates ship within 4 weeks.

SEL CTO panels embody SEL best- known engineering methods and field-tested expertise in mechanical design, cable management, protection, precise time, automation, and communications.

Components and functionalities associated with a specific substation application (e.g., feeder protection and control) are co-located and designed as an application module. Application modules support common protection and automation practices while universal wiring to terminal blocks allows customization to adapt to any common primary equipment configuration and operation practice.

Human error is often referenced as the main cause for events that occur in the power system. With standardized applications, co-located components, adequate space, and improved labeling, SEL CTO panels help increase safety for personnel and reduce the possibility for error.

By organizing components and functionalities into application modules, SEL leverages world-class manufacturing principles to provide a more robust, consistent, and repeatable product.

All components associated with an application module are physically co-located, reducing the possibility for mistakes while simplifying the installation, commissioning and future module additions or upgrades.

Connections are positioned within easy reach for technicians and every wire is labeled at both ends to make connections obvious and to speed up troubleshooting.

Application modules are mechanically assembled, wired, and tested in the production line for faster production and delivery.

All wires are cut, stripped, and crimped on state-of-the-art automated equipment, eliminating waste, guaranteeing repeatability, and ensuring the quality of each crimp.

Details

SEL CTO panels embody SEL best-known engineering methods and field-tested expertise in mechanical design, cable management, protection, precise time, automation, communications, and metering.

Application modules support common protection and automation practices while universal wiring to terminal blocks allows customization flexibility to adapt to any common primary equipment configuration and operation practice.

The SEL Difference

SEL uses the same world-class manufacturing principles for our panels that we use for all our industry-leading products. This allows us to design, manufacture, test, and deliver top-quality and comprehensive panel systems.

Complete vertical integration and standardized application designs help us maintain competitive prices and high quality while still meeting the highest functionality requirements and delivery within weeks, not months.

Design Principles

SEL CTO panels provide the following:

  • Fully redundant protection and breaker failure protection at all voltage levels.
  • Preconfiguration for cybersecurity framework integration.
  • Advanced SEL technology, such as arc-flash protection, zone-interlocked bus protection logic, and negative-sequence overcurrent protection, that is ready to deploy.
  • Simple integration to SCADA and HMI.
  • Continuous monitoring to reduce the possibility of hidden failures and facilitate extended testing intervals.
  • An industrial design for improved human performance.

Design Validation That Guarantees Expected Performance

We build a prototype and test each application module design to ensure it meets functional specifications. This process allows our manufacturing facility to properly document processes and test manufacturing equipment for production.

Drawing Package

SEL CTO panels come with comprehensive information using best practices for documenting protection and control circuitry. With standardization, the level of error-free detail is unmatched compared to what is practical with custom panels. SEL drawing packages are personalized to your substation project and nomenclature and include:

  • Application-specific circuit information.
  • One-line diagram customized with your primary equipment information.
  • AC schematics diagrams documenting relay sensing circuits, protection functions, and space to incorporate customer primary equipment information.
  • DC schematic diagrams with panel control circuits and space to include external connection points from marshalling cabinets and primary equipment.
  • Comprehensive logic diagrams documenting logic settings for the application, including local/remote control and indication, target LEDs, fault protection, alarms, event report triggers, open, close, reclose, and trip.
  • Panel layout drawing containing device locations, dimensions, and anchoring details.
  • Wiring diagram with wiring label nomenclature.
  • Nameplate drawing that includes all labels created and installed in the panel.

Quality

We engineer, manufacture, and test our panels to ensure adequate operation before delivery. When a panel arrives at your site, it is already verified as fully functional.

Warranty and Support

SEL panels are supported by an unmatched ten-year warranty and the industry’s best customer service.

The Firmware IDs for older versions of the firmware can typically be found in Appendix A of the instruction manual.
