Its innovative approach validates the correct operation of the entire protection system by simulating realistic power system events. In addition to common tests, RelaySimTest also reveals settings, logic and design errors in the scheme. This paves the way for improved testing quality and time saving testing procedures.

Modern protective relays use complex algorithms that adapt to networks and failures. Simple function tests are often not sufficient for testing such relays. RelaySimTest covers these new demands with a transient simulation of theprimary power system.

System-based tests are independent from relay type, manufacturer and detailed parameters. The protection behavior is the only thing that counts.
