In a prior article it was announced the successful testing of the traveling-wave functions in the SEL-T400L Time-Domain Line Protection using the Real Time Digital Simulator. This testing showed the dependability and security upfront before releasing the devices in service.

The testing beforehand resulted in a successful restraint of the in-service time-domain line protection for an external fault. Check out the article below!

External Fault Validates Security of SEL-T400L Protection Schemes

Driving down a freeway in Los Angeles and I spotted this transmission line corridor. If you count the number of lines, you will see 10 of them! This is a good reason to disable ground distance. It becomes practically impossible to account for the mutual coupling of all the conductors in your short-circuit program.

Check out a highlight on testing time-domain line protection using real-time digital simulation!
