This module provides ultra-high-speed protection using time-domain technology of traveling waves and incremental quantities as primary functions and complementary phasor-based distance protection, overcurrent protection, directional elements, and pilot protection.View Product Info
This module provides line protection, including distance and pilot protection, as primary functions with additional functions including breaker failure and reclosing for one breaker, sync-check, and DTT.View Product Info
This module provides reliable dc output to power protection, monitoring, and control equipment in the panel by combining up to three ac sources and one dc source into a single control power output. Energy storage capacitors provide ride-through capability and support switch or breaker trip/close application.View Product Info
This module provides independent local control and indication for up to three switching devices. It is also available with rotary control switches.View Product Info
This module provides independent mechanical lockout for the breaker failure protection (86BF) using rotary lockout switches.
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.
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.
SEL CTO panels provide the following:
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.
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:
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.
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.
