NG # 001415-HW-SEL-015
Manufactured by:
The SEL-T401L is a high-performance, easy-to-use line protective relay in a 3U package. Built on the field experience of the SEL-T400L Time-Domain Line Protection, the SEL-T401L delivers unprecedented operating times and includes the complete suite of primary and backup protection functions that you expect in a line protection system. Suitable for a wide range of applications, the SEL-T401L offers an opportunity to reset the complexity of line protection applications with its simple protection philosophies, and reduced settings count.
Specification
- Ultra-High-Speed Protection
- Ultra-High-Resolution Transient Recording
- Unparalleled Fault Locating
Description
You can apply the SEL-T401L on its own or as part of a redundant protection system with other SEL relays without concerns for common-mode failures. The new technology of traveling waves and incremental quantities along with the enhancements and simplifications in phasor-based protection elements make the SEL-T401L protection philosophy, hardware, and software different from other SEL line protective relays. You’ll gain efficiency by using common SEL configuration and integration tools and also benefit from strong diversity in hardware, software, and protection operating principles.
