SEL-7202 configure-to-order (CTO) line protection panels provide the most advanced and fastest protection and control for two-terminal, two-breaker transmission lines using phasors and time-domain technology. Select between phase distance, line current differential, and traveling-wave protection relays to obtain the following features:
This module provides comprehensive line protection and control, including line current differential, distance, and pilot protection as primary functions. Additional functions include overcurrent protection, breaker failure protection for two breakers, reclosing, sync-check, and DTT.
This module provides comprehensive line protection and control, including distance and pilot protection as primary functions. Additional functions include overcurrent protection, breaker failure protection and reclosing for two breakers, sync-check, and DTT.
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.
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.
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.
This module provides independent local control and indication for up to three switching devices. It is also available with rotary control switches.
This module provides independent mechanical lockout for the breaker failure protection (86BF) using rotary lockout switches.
The Firmware IDs for older versions of the firmware can typically be found in Appendix A of the instruction manual.
